Explore genetic algorithms and typeclasses in Scala through a hands-on conference talk recorded at Scala Days Berlin 2016. Dive into the power of typeclasses in functional programming, learning how to attach custom interfaces to existing code. Discover the implementation of genetic algorithms in Scala, with a focus on defining problem-specific typeclasses. Gain insights into testing algorithms using ScalaCheck and witness the creation of visual, creative solutions as the genetic algorithm's fitness function evolves. Follow along with REPL examples, covering topics such as custom types, comparators, type classes, crossover techniques, random mutations, and fitness functions. Enhance your understanding of Scala's functional programming capabilities and explore innovative applications in modern art and image comparison.
