In solver configuration, Simulating Annealing algorithm need to configure more things(acceptor, forager, etc) to validate and execute(Other Local Search algorithms validated).

In OptaPlanner manual, Simulated Annealing doesn't have simple configurations. Simulated Annealing need to set manually acceptor(simulatedAnnealingStartingTemperature) and forager(acceptedCountLimit)

I think you can choose one of two other solution
1. Make text input for configuration
2. Set default value for Simulated Annealing or find validation bug
