| программа ЭВМ для анализа органического синтеза сложных и комплексных молекул (LHASA (Logic and Heuristics Applied to Synthetic Analysis) is a program for synthesis planning, an expert system to assist chemists in designing efficient routes to target molecules for organic synthesis. Operating differently from reaction retrieval systems, LHASA searches its own way in synthesizing known and unknown compounds, using a chemical knowledge base (rather than a database of literature examples). Since LHASA operates in a rigorously retrosynthetic fashion, the knowledge base contains information about retro-reactions (or transforms) rather than reactions. The current version of LHASA (20.3) contains 2271 transforms and 495 so-called tactical combinations.); усл. программа ЭВМ для анализа органического синтеза сложных и комплексных молекул | |||
