Artificial intelligence is everywhere these days. This course teaches you how to implement two types of AI using simple C#. You'll use concepts from biology to evolve solutions to complex problems like optimal subset selection and data ordering.
Certain problems can't be solved by brute force. Combinatorial problems that involve finding an optimal ordering or subset of data can be extremely challenging to solve if the number of items is too large since the time to test each possible solution can often be prohibitive. In this course, you'll learn how to write artificial intelligence code that uses concepts from biology (like evolution, genetic crossover, and mutation) so the software can evolve optimal solutions to complex problems. The code will be written in fairly simple C#, and no external libraries will be used, so you'll understand all of the details. First, you'll learn how to write a genetic algorithm, which is a technique to manipulate data. You'll learn about different ways to represent potential solutions, as well as techniques for evolving solutions over a number of generations. Different types of crossover and mutation will be discussed, as well as various factors related to evaluating each candidate solution's fitness, which influences which candidates are selected for reproduction. After looking at how genetic algorithms can be used to find optimal solutions for data, you'll learn about genetic programming, which uses similar concepts but evolves actual executable code, rather than simply manipulating data. Genetic programming is particularly well-suited to finding an expression that fits a set of training data. The results of this technique can be used for prediction, estimates, and the like. Finally, you'll discover how genetic programming can be used to perform many complex tasks - controlling processes and making decisions, in particular. The code that results can be quite complex, balancing many different competing factors and constraints. By the end of this course, you'll have a solid foundation to apply these concepts to your own programs.

Course Overview Whether it's advanced systems like Google's AlphaGo or even the software that powers voice recognition on your phone, artificial intelligence is everywhere these days. Unfortunately, writing your own AI software has always been difficult. Techniques like neural networks are powerful, but complex, and frequently involve advanced mathematics. Fortunately, there's an alternative. In this course, Understanding Genetic Algorithms and Genetic Programming, you'll learn how to apply concepts from biology to software development. Instead of you, the programmer, coming up with an algorithm the software will evolve its own solutions, which can often solve problems that would be far too complex for traditional programming. Some of the major topics that we will cover include how we can find solutions to complex problems by using populations of candidate solutions, and evolving them over time using concepts like genetic crossover and mutation, how genetic algorithms can be used to find optimal subsets of data, and how they can find optimal orderings of data, and perhaps, most impressively, how you can evolve actual executable code that can be used in your own programs. We'll examine three different applications for this technique, including finding an equation that fits a set of training data, controlling the movement of an object in space, and code to help us make decisions in a game of Texas hold'em poker. By the end of this course you'll understand how to apply these techniques to your own code. Before beginning this course you should be familiar with C#, but please be aware that this course does not require advanced programming skills. In fact, most of the code we will write will be fairly simple. I hope you'll join me as we learn more about this fascinating approach to AI with the Understanding Genetic Algorithms and Genetic Programming course at Pluralsight.
