solveChart {QCA}R Documentation

Reduce the redundant prime implicants

Description

While the minimization procedure finds a certain number of prime implicants, 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
