USA Computing Olympiad
The United States of America Computing Olympiad (USACO) is an online computer programming competition, which serves as qualification for the International Olympiad in Informatics (IOI) in the United States of America. Primarily for secondary school students in the United States, the USACO offers four competitions (December, January, February, US Open) during the academic year. Participants compete in four increasingly difficult divisions (Bronze, Silver, Gold and Platinum), each of which is provided a distinct set of 3 solvable competitive programming problems during each contest. Coding & submitting computer programs can be done in one of four languages: C, C++, Java, and Python. Competitors begin in the Bronze division, and advance through the levels by performing well in their current division. Following the US Open (ran in late March to early April) competition, a week-long summer training camp is held in late May-early June (with around 24-30 top USACO participants ...

Computer Programming
Computer programming is the process of performing a particular computation (or more generally, accomplishing a specific computing result), usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms (usually in a chosen programming language, commonly referred to as coding). The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task (which can be as complex as an operating system) on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the application domain, specialized algori ...

Shortest Path Problem
In graph theory, the shortest path problem is the problem of finding a path between two vertices (or nodes) in a graph such that the sum of the weights of its constituent edges is minimized. The problem of finding the shortest path between two intersections on a road map may be modeled as a special case of the shortest path problem in graphs, where the vertices correspond to intersections and the edges correspond to road segments, each weighted by the length of the segment. Definition The shortest path problem can be defined for graphs whether undirected, directed, or mixed. It is defined here for undirected graphs; for directed graphs the definition of path requires that consecutive vertices be connected by an appropriate directed edge. Two vertices are adjacent when they are both incident to a common edge. A path in an undirected graph is a sequence of vertices P = ( v_1, v_2, \ldots, v_n ) \in V \times V \times \cdots \times V such that v_i is adjacent to v_ for 1 \leq i ...

Canadian Computing Competition
The Canadian Computing Competition (CCC) is an annual programming competition for secondary school students in Canada, organized by the Centre for Education in Mathematics and Computing at the University of Waterloo. Stage 1 is written at high schools and can be written in the programming language of the students' choice, with only a few, such as Maple and Mathematica, disallowed. There are two levels of problems presented, Junior and Senior. The top 20 (or so) students in the Senior division are invited to the University of Waterloo to participate in Stage 2, the Canadian Computing Olympiad (CCO). CCO participants are restricted to languages permitted at the IOI, which currently includes only Java, C and C++. (Pascal was discontinued in 2019). The CCO is used to select students to represent Canada at the IOI. The questions in the CCC are algorithmic in nature, designed to test a student's ability to design and code algorithms rather than their knowledge of APIs or language-sp ...

International Science Olympiad
The International Science Olympiads are a group of worldwide annual competitions in various areas of the formal sciences, natural sciences, and social sciences. The competitions are designed for the 4-6 best high school students from each participating country selected through internal National Science Olympiads, with the exception of the IOL, which allows two teams per country, the IOI, which allows two teams from the hosting country, and the IJSO, which is designed for junior secondary students. Early editions of the Olympiads were limited to the Eastern Bloc, but later they gradually spread to other countries. The Olympiad has no links to the International Olympic Committee nor the US sponsored Science Olympiad. Overview The Olympiads themselves are separate competitions each with its own organizing body, even though they are loosely grouped together as "ISOs". The aims of each ISO are to promote a career in science; to challenge the brightest students from around the world; an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central European Olympiad In Informatics
The Central European Olympiad in Informatics (CEOI) is an annual informatics competition for secondary school students. Each of the participating central European countries (plus one or two guest countries, and a local team from the host area) sends a team of up to four contestants, a team leader and a deputy team leader. The contestants compete individually, i.e. a team score is not calculated. Competitors are selected through national competitive programming contests. The contest consists of two days computer programming, solving problems of an algorithmic nature. The structure of these competition days is described in the article about the International Olympiad in Informatics (IOI), which served as a role model for the more local CEOI. The first CEOI was held in 1994 in Romania (founder of the CEOI), five years after the first IOI. List of CEOI websites and locations CEOI 2021was supposed to be held in Zagreb, Croatia, was held online instead (1- 5 September 2021). CEOI 2020w ...

Ice Cream
Ice cream is a sweetened frozen food typically eaten as a snack or dessert. It may be made from milk or cream and is flavoured with a sweetener, either sugar or an alternative, and a spice, such as cocoa or vanilla, or with fruit such as strawberries or peaches. It can also be made by whisking a flavored cream base and liquid nitrogen together. Food coloring is sometimes added, in addition to stabilizers. The mixture is cooled below the freezing point of water and stirred to incorporate air spaces and to prevent detectable ice crystals from forming. The result is a smooth, semi-solid foam that is solid at very low temperatures (below ). It becomes more malleable as its temperature increases. The meaning of the name "ice cream" varies from one country to another. In some countries, such as the United States, "ice cream" applies only to a specific variety, and most governments regulate the commercial use of the various terms according to the relative quantities of the main in ...

Proctor
Proctor (a variant of ''procurator'') is a person who takes charge of, or acts for, another. The title is used in England and some other English-speaking countries in three principal contexts: * In law, a proctor is a historical class of lawyers, and the King's (or Queen's) Proctor is a senior government lawyer. * In religion, a proctor represents the clergy in Church of England dioceses. * In education, proctor is the name of university officials in certain universities. In the United States and some other countries, the word "proctor" is frequently used to describe someone who supervises an examination (i.e. a supervisor or invigilator) or dormitory. Law England A proctor was a legal practitioner in the ecclesiastical and admiralty courts in England. These courts were distinguished from the common law courts and courts of equity because they applied "civil law" derived from Roman law, instead of English common law and equity. Historically, proctors were licensed by the Arc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weighted
A weight function is a mathematical device used when performing a sum, integral, or average to give some elements more "weight" or influence on the result than other elements in the same set. The result of this application of a weight function is a weighted sum or weighted average. Weight functions occur frequently in statistics and analysis, and are closely related to the concept of a measure. Weight functions can be employed in both discrete and continuous settings. They can be used to construct systems of calculus called "weighted calculus" and "meta-calculus".Jane Grossma''Meta-Calculus: Differential and Integral'' , 1981. Discrete weights General definition In the discrete setting, a weight function w \colon A \to \R^+ is a positive function defined on a discrete set A, which is typically finite or countable. The weight function w(a) := 1 corresponds to the ''unweighted'' situation in which all elements have equal weight. One can then apply this weight to various concep ...

Computer Storage
Computer data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. The central processing unit (CPU) of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but less expensive and larger options further away. Generally, the fast volatile technologies (which lose data when off power) are referred to as "memory", while slower persistent technologies are referred to as "storage". Even the first computer designs, Charles Babbage's Analytical Engine and Percy Ludgate's Analytical Machine, clearly distinguished between processing and memory (Babbage stored numbers as rotations of gears, while Ludgate stored numbers as displacements of rods in shuttles). This distinction was extended in the Von Neumann a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Run Time (program Lifecycle Phase)
In computer science, runtime, run time, or execution time is the final phase of a computer programs life cycle, in which the code is being executed on the computer's central processing unit (CPU) as machine code. In other words, "runtime" is the running phase of a program. A runtime error is detected after or during the execution (running state) of a program, whereas a compile-time error is detected by the compiler before the program is ever executed. Type checking, register allocation, code generation, and code optimization are typically done at compile time, but may be done at runtime depending on the particular language and compiler. Many other runtime errors exist and are handled differently by different programming languages, such as division by zero errors, domain errors, array subscript out of bounds errors, arithmetic underflow errors, several types of underflow and overflow errors, and many other runtime errors generally considered as software bugs which may or may ...

Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource shari ...
