Description
Sets the maximum number of nodes solved before the algorithm terminates without reaching optimality. When this parameter is set to 0 (zero), CPLEX completes processing at the root; that is, it creates cuts and applies heuristics at the root. When this parameter is set to 1 (one), it allows branching from the root; that is, nodes are created but not solved.
Values
Any nonnegative integer; default: 9223372036800000000.
