solveChart: Reduce the redundant prime implicants

Description

While the minimization procedure find a certain number of prime implicants but not all of them are necessary as some are already covered by others (therefore redundant). This function further reduces the number of prime implicants for a minimum solution.

Usage

solveChart(chart)

Arguments

chart

the prime implicants chart, a matrix with TRUE/FALSE values

Value

• a matrix containing row indices of all possible solutions
