  12. 2.1 Definition of firework • Good firework: firework can generate a big population of sparks within a small range. • Bad firework: firework that generate a small population of sparks within a big range. • The next will introduce the operators in FWA.

  13. Number of sparks Number of sparks generated by each firework (Xi) is defined as follows: Fireworks with better fitness values produce more sparks while those with worse fitness values produce small sparks.

  14. Amplitude of explosion Amplitude of explosion is defined by The amplitude of explosion of a good firework is smaller than that of a bad one.

  36. 3.2 Dynamic Search FWA (dynFWA) • CEC 2013 • 28 functions

  37. 3.3 Raising Information Utilization Rate • Typically, most swarm/evolutionary algorithms share the same framework consisting of two steps: • New individuals are produced • Old individuals are eliminated. • In the first step, new information is acquired; while in the second step, some information about the objective function is abandoned. • The performances of these algorithms depend intensively on how and to what extent the information is utilized before it is abandoned. Therefore, • By raising information utilization rate, full usage of the information acquired by a heuristic algorithm in the search process is helpful for better guiding future behaviors.
