.. note::
    * The server component will split strategy executions in chunks which are distributed among the different workers. **pyalgotrade.optimizer.server.Server.defaultBatchSize** controls the chunk size.
    * The :meth:`pyalgotrade.strategy.BaseStrategy.getResult` method is used to select the best strategy execution. You can override that method to rank executions using a different criteria.
