Expansion of Symbolic Determinants with Computer
A new type of algorithm is introduced for constructing Expansion of symbolic determinants which encode answers to mathematical problems. Examples include problems from the NP-Complete class, which are widely considered to be harder than those in the problem classes previously addressed. In particular, algorithms are presented that generate expansions of symbolic determinants and the sign (+,-) of each term given their patterns of zero entries. This is wellknown to be exponentially more difficult than evaluating determinants whose entries are merely numerical. Prior approaches to computer computation were impractical for large problems. Our new approach to the production of the solution is based permutation method, recursive programming technology.
