This presentation discusses conformational Genetic Algorithms. The conventional Gray Coding of torsional angles of molecules in pharmacophore elucidation tool GASP was substituted with a Biased Gray Coding (BGC). BGC explores torsional angles of molecules close to certain predetermined values where one is at better odds of finding a good solution. Results of GASP with BGC are compared with conventional GASP Gray Coding results.
