Parameters

p_status

Type:  SystemInt32
The status after the relaxation:

• 1: relaxed problem is infeasible;
• 2: relaxed problem is unbounded;
• 3: solution of the relaxed problem regarding the original objective is nonoptimal;
• 4: error (when return code is nonzero);
• 5: numerical instability;
• 6: analysis of an infeasible relaxation was performed, but the relaxation is feasible.

lepref

Type:  SystemDouble
Array of size ROWS containing the preferences for relaxing the less or equal side of row.

gepref

Type:  SystemDouble
Array of size ROWS containing the preferences for relaxing the greater or equal side of a row.

lbpref

Type:  SystemDouble
Array of size COLS containing the preferences for relaxing lower bounds.

ubpref

Type:  SystemDouble
Array of size COLS containing preferences for relaxing upper bounds.

phase2

Type:  SystemChar
Controls the second phase of optimization:

• o: use the objective sense of the original problem (default);
• x: maximize the relaxed problem using the original objective;
• f: skip optimization regarding the original objective;
• n: minimize the relaxed problem using the original objective;
• i: if the relaxation is infeasible, generate an irreducible infeasible subset for the analys of the problem;
• a: if the relaxation is infeasible, generate all irreducible infeasible subsets for the analys of the problem.

delta

Type:  SystemDouble
The relaxation multiplier in the second phase -1.

flags

Type:  SystemString
Specifies flags to be passed to the Optimizer.
