Va. Nepomniaschy et Aa. Sulimov, PROBLEM-ORIENTED VERIFICATION SYSTEM AND ITS APPLICATION TO LINEAR ALGEBRA PROGRAMS, Theoretical computer science, 119(1), 1993, pp. 173-185
The problem-oriented verification system SPECTRUM using the set of lin
ear algebra programs as the problem area is described. Its main compon
ent is a special prover which uses knowledge base and approximate deci
sion procedures. To simplify the program specification, a method of lo
op-invariant elimination is used.
