Aviezri Fraenkel
Aviezri Siegmund Fraenkel ( he, אביעזרי פרנקל) (born June 7, 1929) is an Israeli mathematician who has made contributions to combinatorial game theory. Biography Aviezri Siegmund Fraenkel was born in Munich, Germany, to a Jewish family, which then moved to Switzerland soon thereafter. In 1939 his family moved once more, to Jerusalem. Fraenkel is married to Shaula and father of six. One of his grandchildren, Yaacov Naftali Fraenkel, was kidnapped and murdered by Hamas members in June 2014. In 2018, in respect for his life's work, Fraenkel was given the highly regarded honor to light one of twelve torches—one for each of Twelve Tribes—at the State of Israel's televised opening ceremony on Har Herzl, Jerusalem, in celebration of Israel's 70th Independence Day (which in 2018, fell on Wednesday evening April 18 – Thursday evening April 19). Academic career Fraenkel received his Ph.D. in 1961 from the University of California, Los Angeles. He was a recipient of th ...

WEIZAC
WEIZAC (''Weizmann Automatic Computer'') was the first computer in Israel, and one of the first large-scale, stored-program, electronic computers in the world. It was built at the Weizmann Institute during 1954–1955, based on the Institute for Advanced Study (IAS) architecture developed by John von Neumann and was operational until the end of 1963. WEIZAC was widely used by Israeli scientists and researchers and helped with the advancement of science and technology in the young nation. As with all computers of its era, it was a one of a kind machine that could not exchange programs with other computers (even other IAS machines). The beginning The WEIZAC project was initiated by Prof. Chaim L. Pekeris, who worked at the IAS at the time von Neumann's IAS machine was being designed. Chaim Weizmann, Israel's future first president, asked Pekeris to establish the Department of Applied Mathematics at the Weizmann Institute, and Pekeris wanted to have a similar computer available t ...

Combinatorial Game Theorists
Combinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures. It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science. Combinatorics is well known for the breadth of the problems it tackles. Combinatorial problems arise in many areas of pure mathematics, notably in algebra, probability theory, topology, and geometry, as well as in its many application areas. Many combinatorial questions have historically been considered in isolation, giving an ''ad hoc'' solution to a problem arising in some mathematical context. In the later twentieth century, however, powerful and general theoretical methods were developed, making combinatorics into an independent branch of mathematics in its own right. One of the oldest and most accessible parts of combinatorics is gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haganah Members
Haganah ( he, הַהֲגָנָה, lit. ''The Defence'') was the main Zionist paramilitary organization of the Jewish population ("Yishuv") in Mandatory Palestine between 1920 and its disestablishment in 1948, when it became the core of the Israel Defense Forces (IDF). Formed out of previous existing militias, its original purpose was to defend Jewish settlements from Arab attacks, such as the riots of 1920, 1921, 1929 and during the 1936–1939 Arab revolt in Palestine. It was under the control of the Jewish Agency, the official governmental body in charge of Palestine's Jewish community during the British Mandate. Until the end of the Second World War, Haganah's activities were moderate, in accordance with the policy of havlaga ("self-restraint"), which caused the splitting of the more radical Irgun and Lehi. The group received clandestine military support from Poland. Haganah sought cooperation with the British in the event of an Axis invasion of Palestine through North ...

Jewish Emigrants From Nazi Germany To Mandatory Palestine
Jews ( he, יְהוּדִים, , ) or Jewish people are an ethnoreligious group and nation originating from the Israelites Israelite origins and kingdom: "The first act in the long drama of Jewish history is the age of the Israelites""The people of the Kingdom of Israel and the ethnic and religious group known as the Jewish people that descended from them have been subjected to a number of forced migrations in their history" and Hebrews of historical Israel and Judah. Jewish ethnicity, nationhood, and religion are strongly interrelated, "Historically, the religious and ethnic dimensions of Jewish identity have been closely interwoven. In fact, so closely bound are they, that the traditional Jewish lexicon hardly distinguishes between the two concepts. Jewish religious practice, by definition, was observed exclusively by the Jewish people, and notions of Jewish peoplehood, nation, and community were suffused with faith in the Jewish God, the practice of Jewish (religious) ...

Algorithms
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm can be expressed within a finite amount of space and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Complexity
Complexity characterises the behaviour of a system or model whose components interaction, interact in multiple ways and follow local rules, leading to nonlinearity, randomness, collective dynamics, hierarchy, and emergence. The term is generally used to characterize something with many parts where those parts interact with each other in multiple ways, culminating in a higher order of emergence greater than the sum of its parts. The study of these complex linkages at various scales is the main goal of complex systems theory. The intuitive criterion of complexity can be formulated as follows: a system would be more complex if more parts could be distinguished, and if more connections between them existed. Science takes a number of approaches to characterizing complexity; Zayed ''et al.'' reflect many of these. Neil F. Johnson, Neil Johnson states that "even among scientists, there is no unique definition of complexity – and the scientific notion has traditionally been conveyed ...

Analysis Of Algorithms
In computer science, the analysis of algorithms is the process of finding the computational complexity of algorithms—the amount of time, storage, or other resources needed to execute them. Usually, this involves determining a function that relates the size of an algorithm's input to the number of steps it takes (its time complexity) or the number of storage locations it uses (its space complexity). An algorithm is said to be efficient when this function's values are small, or grow slowly compared to a growth in the size of the input. Different inputs of the same size may cause the algorithm to have different behavior, so best, worst and average case descriptions might all be of practical interest. When not otherwise specified, the function describing the performance of an algorithm is usually an upper bound, determined from the worst case inputs to the algorithm. The term "analysis of algorithms" was coined by Donald Knuth. Algorithm analysis is an important part of a broader ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bar Ilan Responsa Project
The Bar Ilan Responsa Project (the ''Global Jewish Database'') is a collection of Jewish texts in Hebrew, sold on CD and more recently on USB flash-drive by Bar-Ilan University (in Ramat Gan, Israel). Background The database consists of one of the world's largest electronic collections of Jewish texts in Hebrew. It includes numerous works from the Responsa Literature (rabbinic case-law rulings). The database also includes the Bible and the Talmud (with commentaries); articles about Jewish law and customs; Maimonides' Mishneh Torah and the Shulchan Aruch with main commentaries; Zohar, Midrashim, and the Talmudic Encyclopedia. Today the Responsa Project CD-ROM contains more than 90,000 Responsa and more than 420,000 hypertext links between the databases totalling 200 million words. The project was founded by Aviezri Fraenkel who served as its initial director (1963–1974), and subsequent director Yaacov Choueka (1975–1986), as cited by the Israel Prize committee. Cur ...
