Seminole Gulf Railway
The Seminole Gulf Railway is a short line railroad, 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, Florida, Arcadia south to Naples, Florida, North Naples via Punta Gorda, Florida, Punta Gorda, Fort Myers, Florida, Fort Myers, Estero, Florida, Estero, and Bonita Springs, Florida, Bonita Springs. The company's other line, the Sarasota Division, runs from Oneco, Florida, Oneco south through Sarasota, Florida, 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 had a commonly owned affiliated company, the Bay Colony Railroad, Bay Colony Railroad Corp. , which was based in southeastern Massachus ...

Generalized LR Parser
A GLR parser (generalized left-to-right rightmost derivation parser) 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 used and more flexible parsers for extensible programming l ...

Lexical Analysis
Lexical tokenization is conversion of a text into (semantically or syntactically) meaningful ''lexical tokens'' belonging to categories defined by a "lexer" program. In case of a natural language, those categories include nouns, verbs, adjectives, punctuations etc. In case of a programming language, the categories include identifiers, operators, grouping symbols, data types and language keywords. Lexical tokenization is related to the type of tokenization used in large language models (LLMs) but with two differences. First, lexical tokenization is usually based on a lexical grammar, whereas LLM tokenizers are usually probability-based. Second, LLM tokenizers perform a second step that converts the tokens into numerical values. Rule-based programs A rule-based program, performing lexical tokenization, is called ''tokenizer'', or ''scanner'', although ''scanner'' is also a term for the first stage of a lexer. A lexer forms the first phase of a compiler frontend in processing. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
