Instances of this class are capable of solving optimization problems of the following types: ◆ Linear Programs (LPs), ◆ Mixed Integer Linear Programs (MILPs), ◆ Mixed Integer Programs (MIPs), ◆ Quadratic Programs (QPs), ◆ Mixed Integer Quadratic Programs (MIQPs), ◆ Quadratically Constrained Programs (QCPs); ILOG CPLEX C++ API 9.0 REFERENCE M ANUAL 14
◆ Mixed Integer Quadratically Constrained Programs (MIQCPs). An instance of IloCplex can extract and solve models consisting of the following Concert Technology extractables: Extractable Class Used to Model IloNumVar numeric variables IloSemiContVar semi-continuous or semi-integer variables IloObjective at most one objective function with linear, piecewise linear, or quadratic expressions IloRange range constraints with linear or piecewise linear expressions IloConstraint ranged constraints of the form expr1relationexpr, where expr1 indicates a linear, logical, or quadratic expression and the relation less than or equal to or the relation greater than or equal to; constraints can be combined by logical operators IloConversion variable type conversions IloModel submodels IloSOS1 special ordered sets of type 1 IloSOS2 special ordered sets of type 2 IloAnd constraint clauses What is special about this set of extractable classes recognized by IloCplex is that models consisting of these objects can be transformed into mathematical programming problems of the form: When all variables are continuous and Q is zero, problems of this form are known as Linear Programs (LPs). If Q is not zero, such problems are known as Quadratic Programs (QPs). If any variables are integer, semi-continuous, or Boolean, such problems are called Mixed Integer Programs (MIPs). A MIP with a zero Q matrix is called a Mixed Integer Linear Program (MILP), and a MIP with a non-zero Q is called a Mixed Integer Quadratic Program (MIQP). If there are quadratic constraints in the problem, and its variables are continuous, it is known as a Quadratically Constrained ILOG CPLEX C++ API 9.0 REFERENCE M ANUAL 15
