Genetic reinforcement learning through symbiotic evolution for fuzzy controller design

Abstract: Abstract-An efficient genetic reinforcement learning algorithm for designing fuzzy controllers is proposed in this paper. The genetic algorithm (GA) adopted in this paper is based upon symbiotic evolution which, when applied to fuzzy controller design, complements the local mapping property of a fuzzy rule. Using this Symbiotic-Evolution-based Fuzzy Controller (SEFC) design method, the number of control trials, as well as consumed CPU time, are considerably reduced when compared to traditional GA-based fuzzy c… Show more

“…In SOA, to prevent suitable selection times from falling into the local optimal solution, we use two different actions to update V M k . Such actions are defined in the following equations: if Accumulator ≤ SOATimes, then do Steps 1 to 3, (25) if Best Fitnessg = Best Fitness, then Accumulator = Accumulator + 1, (26) if Accumulator > SOATimes, then do Step 0 and Accumulator = 0, (27) where SOATimes is a predefined value, Best_Fitness g represents the best fitness value of the best combination of chromosomes in the gth generation, and Best_Fitness represents the best fitness value of the best combination of chromosomes in the current generations. If Equation 27 is satisfied, then it indicates that the suitable selection times may fall into the local optimal solution.…”

“…In the remaining chromosomes in each group, this study uses the roulette-wheel selection method [26] for this reproduction process. The well-performed chromosomes in the top half of each group [27] proceed to the next generation. The other half is created by executing crossover and mutation operations on chromosomes in the top half of the parent individuals.…”

“…Since the RL has the capability to simulate the behavior of human beings when making decisions, to learn and accumulate experience through interaction with the environment, and to make corresponding actions when encountering various states in order to achieve the set goals. Hence, the reinforcement learning often is employed to enable the continuous learning and evolution of fuzzy systems, such as adjusting the attribution function [18], changing the number of rules [19], etc. In [20], Berenji used reinforcement learning combined with the fuzzy system to adjust the attribution function, so that the fuzzy system can be established more automatically.…”

“…Μία άλλη σημαντική οικογένεια αλγόριθμων που ακολουθεί τη στρατηγική IRL είναι αυτή LiBGFC που προέρχεται από τον αλγόριθμο Linguistic Boosted Genetic Fuzzy Classifier (LiBGFC) [461]. Μία διαφορετική αλλά ενδιαφέρουσα προσέγγιση προτάθηκε στην εργασία [445], όπου και Συμβιωτική εξέλιξη εξετάστηκε η χρήση της συμβιωτικής εξέλιξης [464,465]…”
