In this chapter, we discussed functions, what they are, and why we use them. We developed a very powerful and flexible application with which to test function optimization. We also showed you the complete process of adding a new function and how to run it once added. You are now free to add as many new functions as you like; just follow the process outlined herein and you should have no problems.
In the next chapter, we are going to learn how to replace back propagation with particle swarm-optimized algorithms, so hold on to your hats!
