Description
Decides what CPLEX reports to the screen during mixed integer optimization (MIP). The amount of information displayed increases with increasing values of this parameter. A setting of 0 (zero) causes no node log to be displayed until the optimal solution is found. A setting of 1 (one) displays an entry for each integer feasible solution found. Each entry contains the value of the objective function, the node count, the number of unexplored nodes in the tree, and the current optimality gap. A setting of 2 also generates an entry for every n-th node (where n is the setting of the MIPInterval
parameter). A setting of 3 additionally generates an entry for every n-th node giving the number of cuts added to the problem for the previous MIPInterval
number of nodes. A setting of 4 additionally generates entries for the LP root relaxation according to the setting of the simplex display. A setting of 5 additionally generates entries for the LP subproblems, also according to the setting of the simplex display.
