removeMinimalClassCardinalities: Remove minimal class cardinality restrictions

Description Usage Arguments Value Examples

Description

This function allows to remove defined minimal cardinality of particular classes.

Usage

1

Arguments

problem

Problem from which preference information will be removed.

...

Two-element vectors and/or integers. Each argument represents restriction to remove. If c(i, j) vector was provided then defined minimal cardinality j for class C_i will be removed. In case where single value i was given a restriction for class a_i will be removed regardless of minimal cardinality value. If a specific restriction was not found nothing will happen.

Value

Problem with removed preference information.

# 4 alternatives, 2 gain criteria, 3 classes, monotonously increasing

problem <- buildProblem(perf, 3, FALSE, c('g', 'g'), c(0, 0))

# set minimal class cardinalities:
# at least one alternative has to be assigned to class 2
# and at least one alternative has to be assigned to class 3
problem <- addMinimalClassCardinalities(problem, c(2, 1), c(3, 1))
# remove defined restriction for class 2
problem <- removeMinimalClassCardinalities(problem, 2)
