Our fuzzy inference system cause the local search operator focus on locations that solutions haven’t good performance, so number of fitness function call will be decreased. Genetic Algorithms and Fuzzy Logic 2. What is fuzzy search? Fuzzy search is a way to search strings based on how approximate the strings match. I've personally needed to use this but all of the other Java implementations out there either had a crazy amount of dependencies, or simply did not output the correct results as the python one, so I've decided to properly re-implement this in Java. Instructions are given for observing and tuning the algorithm through the user interface. For achieving more accuracy in these two latter systems an optimization algorithm had to be applied. particle swarm optimization.
