In computing, Lhasa (Japanese pronunciation: [ɾasa]) refers to two different applications.

File archives

Lhasa is a Japanese computer program[when?] used to "unpack" or decompress compressed files in LHA, ZIP, and other formats.

Synthetic analysis

It is also the name of a computer program developed[when?] in the research group of Elias James Corey at the Harvard University Department of Chemistry which uses AI techniques to discover sequences of reactions which may be used to synthesize a compound. LHASA in this case is an acronym for Logic and Heuristics Applied to Synthetic Analysis. This program was one of the first to use a graphical interface to input and display chemical structures.
