Refine and Validate Optimization

Add a feedback loop to your AutoGen system. After the 'Code Optimizer' proposes a solution, simulate its 'execution' or 'profiling'. The 'Performance Analyst' should then evaluate the simulated results against the initial targets. If the targets are not met, the agents should engage in another round of deep reasoning, profiling, and code generation to refine the optimization strategy. Document the iterative process and how agents adapt their approach.
