On : version, PromoPlan


When running promotion optimizer on certain promotions, the process fails during the phase of solving the model, without finding solution. The error they are getting is the following:
  "ilog.concert.IloException: CPLEX Error 1001: Out of memory."

Please note that promotion optimizer is working for many different scenarios but fail for just some promotions. The difference between working and non working promotion is mainly the populated combinations. Non working optimization occur on larger populations.
Customer has tried the following:
1. setting the opti_value_steps anywhere between 29-59
2. setting JVM memory anywhere between 500MB and 4000MB
3. changing the optimization inputs (dates, goal, method, etc.)
4. They have the JVM memory set to JAVA_OPTS = -Xmx1256m . If increase the JVM memory to Xmx3052M, collaborator does not load.

Promotion Optimization to work with promotions having more combinations
