Abstract: A method for searching the web comprising an off-line phase for generating a numerical score for at least one term within a document retrieved from the web, and an on-line phase comprising accessing the numerical score for the at least one term when the at least one term is used as a search term within a query. The numerical score is used to identify documents to include in a search result.

Abstract: Method and apparatus for designing a synthesis route for a target molecule is provided. The method for designing a synthesis route for a target molecule comprises: generating a plurality of individuals, wherein each individual encodes a synthesis route; decoding each individual to produce a synthesis route comprising at least one reactant molecules and at least one reaction; and determining how well the synthesis route satisfies a design goal. A computer readable medium containing instructions for a computer program executable by the computer to perform a method for designing a synthesis route for a target molecule is also provided. The apparatus comprises a parallel computer system for executing instructions of a computer program to perform a method for designing a synthesis route for a target molecule.
