When the Optimizer process is running and calculating the solution, the Anaplan model is locked. We recommend that you test in a sandbox or test environment. If a problem is so complex that the Optimizer processes indefinitely or times out, consider separating the Optimization model from the production model.
When you set up Optimizer, you must specify a time-out setting in seconds to prevent the action from running indefinitely until canceled. The default setting is five minutes (300 seconds) and the maximum setting is four hours (14,400 seconds). An optimizer action always ends after four hours, even if you specify a longer time-out.
For performance analysis, consider isolating the inputs of your optimization problem (objective, variable, and constraints) into distinct modules so that you can easily identify them.
