identify_epi: Identify Essential Prime Implicants from multiple solutions

In TSQCA: Threshold Sweep Extensions for Qualitative Comparative Analysis

Identify Essential Prime Implicants from multiple solutions

Description

Finds terms that appear in ALL solutions (EPIs) versus terms that appear in only some solutions (SPIs).

Usage

identify_epi(solutions)

Arguments

solutions

List of solution vectors. Each element is a character vector of terms for one solution.

Value

List with:

• epi — Essential prime implicants (in all solutions)

• spi — Selective prime implicants (in some solutions)

• n_solutions — Number of solutions

Examples

solutions <- list(
  c("A*B", "C", "D"),
  c("A*B", "C", "E"),
  c("A*B", "C", "F")
)
result <- identify_epi(solutions)
# result$epi = c("A*B", "C")
# result$spi = c("D", "E", "F")
