Seminole Gulf Railway
The Seminole Gulf Railway is a short line freight and passenger excursion railroad headquartered in Fort Myers, Florida, that operates two former CSX Transportation railroad lines in Southwest Florida. The company's Fort Myers Division, which was previously the southernmost segment of CSX's Fort Myers Subdivision, runs from Arcadia south to North Naples via Punta Gorda, Fort Myers, Estero, and Bonita Springs. The company's other line, the Sarasota Division, runs from Oneco south through Sarasota. Seminole Gulf acquired the lines in November 1987 and operates its own equipment. The company's first train departed Fort Myers on November 14, 1987. The Seminole Gulf Railway has a commonly owned affiliated company, the Bay Colony Railroad Corp. , which is based in southeastern Massachusetts. Current operations Seminole Gulf Railway is one of two freight railroads operating in Southwest Florida (the other is South Central Florida Express, who operates tracks farther inland ...

Generalized LR Parser
A GLR parser (GLR standing for "Generalized LR", where L stands for "left-to-right" and R stands for "rightmost (derivation)") is an extension of an LR parser algorithm to handle non-deterministic and ambiguous grammars. The theoretical foundation was provided in a 1974 paper by Bernard Lang (along with other general Context-Free parsers such as GLL). It describes a systematic way to produce such algorithms, and provides uniform results regarding correctness proofs, complexity with respect to grammar classes, and optimization techniques. The first actual implementation of GLR was described in a 1984 paper by Masaru Tomita, it has also been referred to as a "parallel parser". Tomita presented five stages in his original work, though in practice it is the second stage that is recognized as the GLR parser. Though the algorithm has evolved since its original forms, the principles have remained intact. As shown by an earlier publication, Lang was primarily interested in more easily use ...

Lexical Analysis
In computer science, lexical analysis, lexing or tokenization is the process of converting a sequence of characters (such as in a computer program or web page) into a sequence of ''lexical tokens'' (strings with an assigned and thus identified meaning). A program that performs lexical analysis may be termed a ''lexer'', ''tokenizer'', or ''scanner'', although ''scanner'' is also a term for the first stage of a lexer. A lexer is generally combined with a parser, which together analyze the syntax of programming languages, web pages, and so forth. Applications A lexer forms the first phase of a compiler frontend in modern processing. Analysis generally occurs in one pass. In older languages such as ALGOL, the initial stage was instead line reconstruction, which performed unstropping and removed whitespace and comments (and had scannerless parsers, with no separate lexer). These steps are now done as part of the lexer. Lexers and parsers are most often used for compilers, but ...
