# 4 alternatives, 2 gain criteria, 3 classes, monotonously increasing
# and general marginal value functions

problem <- buildProblem(perf, 3, FALSE, c('g', 'g'), c(0, 0))
# add assignment examples: alternative 1 to class at least as good as class 2
# and alternative 2 to class at least as good as class 3
