The Dynamic programming optimizer has the following structure: It has a PlanSpaceClass object. This is an array of PlanTableClass objects. Each PlanTableClass holds LogicalPlans for joins of k relations (k is fixed for each PlanTableClass, and different across PlanTableClasses). Each LogicalPlan corresponds to a logical partial join result, and leads to a number of PhysicalPlans. DynOptimizer is a sub-class of RelSPJCostBasedOpt because it differs only in the Optimize() and GeneratePlanOp() methods. Importantly, it uses the same format to specify the final plan.
