alldiffinferencelevel Inference level for 'alldiff' constraints. Possible values: 0 = default 1 = low 2 = basic 3 = medium 4 = extended branchlimit Limit on the number of branches made before terminating a search. Default = no limit. choicepointlimit Limit on the number of choice points created before terminating a search. Default = no limit. constraintaggregation 0 or 1 (default 1): Whether to aggregate basic constraints. debugexpr 0 or 1 (default 0): Whether to print debugging information for expression trees. defaultinferencelevel Default inference level for constraints. Possible values: 1 = low 2 = basic 3 = medium 4 = extended distributeinferencelevel Inference level for 'distribute' constraints. Possible values: 0 = default 1 = low 2 = basic 3 = medium 4 = extended dynamicprobing Use probing during search. Possible values: -1 = auto (default) 0 = off 1 = on dynamicprobingstrength Effort dedicated to dynamic probing as a factor of the total search effort. Default = 0.03. faillimit Limit on the number of failures allowed before terminating a search. Default = no limit. logperiod Specifies how often the information in the search log is displayed. logverbosity Verbosity of the search log. Possible values: 0 = quiet (default) 1 = terse 2 = normal 3 = verbose mipdisplay Frequency of displaying CPLEX branch-and-bound information (for optimizing integer variables): 0 (default) = never 1 = each integer feasible solution 2 = every "mipinterval" nodes 3 = every "mipinterval" nodes plus information on LP relaxations (as controlled by "display") 4 = same as 2, plus LP relaxation info. 5 = same as 2, plus LP subproblem info. mipinterval Frequency of node logging for mipdisplay 2 or 3. Default = 1. multipointnumberofsearchpoints Number of solutions for the multi-point search algorithm. Default = 30. optimalitytolerance Absolute tolerance on the objective value. Default = 0. optimizer Specifies which optimizer to use. Possible values: auto = CP Optimizer if the problem has nonlinear objective/constraints or logical constraints, CPLEX otherwise (default) cp = CP Optimizer cplex = CPLEX Optimizer outlev Synonym for "logverbosity". propagationlog Level of propagation trace reporting. Possible values: 0 = quiet (default) 1 = terse 2 = normal 3 = verbose randomseed Seed for the random number generator. Default = 0. relativeoptimalitytolerance Relative tolerance on the objective value. Default = 1e-4. restartfaillimit Number of failures allowed before restarting search. Default = 100. restartgrowthfactor Increase of the number of allowed failures before restarting search. Default = 1.05. searchtype Type of search used for solving a problem. Possible values: 0 = depthfirst 1 = restart (default) 2 = multipoint solutionlimit Limit on the number of feasible solutions found before terminating a search. Default = no limit. temporalrelaxation 0 or 1 (default 1): Whether to use temporal relaxation. timelimit Limit on the CPU time spent solving before terminating a search. Default = no limit. timemode Specifies how the time is measured in CP Optimizer. Possible values: 0 = cputime (default) 1 = elapsedtime timing 0 or 1 (default 0): Whether to display timings for the run. usenumberof 0 or 1 (default 1): Whether to consolidate 'numberof' expressions by use of IloDistribute constraints. version Single-word phrase: report version details before solving the problem. wantsol In a stand-alone invocation (no -AMPL on the command line), what solution information to write. Sum of 1 = write .sol file 2 = primal variables to stdout 4 = dual variables to stdout 8 = suppress solution message workers Number of workers to run in parallel to solve a problem. In addition to numeric values this option accepts the value "auto" since CP Optimizer version 12.3. Default = 1.
