Maximal Number of Nodes
Type : Integer
Range : {0 .. 2147483647}
Default : 2147483647
This option sets the maximum number of nodes solved before the algorithm terminates without reaching optimality. When this option is set to 0, CPLEX completes processing at the root; that is, it creates cuts and applies heuristics at the root. When this option is set to 1, it allows branching from the root; that is, nodes are created but not solved.
