SCVarData Struct Reference

Detailed Description

data structure to store information of a semicontinuous variable

For a variable x (not stored in the struct), this stores the data of nbnds implications bvars[i] = 0 -> x = vals[i] bvars[i] = 1 -> lbs[i] <= x <= ubs[i] where bvars[i] are binary variables.
