Setting CP parameters

How to set a parameter value by adding script statements to the model.

The preferred way to set CP parameters is from the IDE settings editor. However, it is sometimes convenient to set a parameter value by adding script statements to the model.

The IBM ILOG Script syntax to change a CP parameter is:

cp.param.paramName = “paramvalue”

For example:

cp.param.DefaultInferenceLevel = “Low”

or (from the model timetabling.mod):

   var p = cp.param;
   p.logPeriod = 10000;
   p.searchType = "DepthFirst";
   p.timeLimit = 600;

See Constraint programming options in Parameters and settings in OPL for a detailed description of each parameter.
