The symmetric cardinality constraint is described in terms of a set of variables X = {x1, . . . , xk}, which take their values as subsets of V = {v1, . . . , vn}. It constraints the cardinality of the set assigned to each variable to be in an interval [lxi , uxi ] and at the same time it restricts the number of occurrences of each value vj ∈ V in the sets… CONTINUE READING
