Documents

• Meta-heuristic Categories: (Based on this article: link)

  • Evolutionary-based: Idea from Darwin's law of natural selection, evolutionary computing
  • Swarm-based: Idea from movement, interaction of birds, organization of social ...

  • Music-based: Idea from music instrument
  • Probabilistic-base: Probabilistic based algorithm
  • Dummy: Non-sense algorithms and Non-sense papers (code proofs)

• DBSP: Difference Between Sequential and Parallel training mode, the results of some algorithms may various due to the training mode.

  • significant: The results will be very different (because the selecting process - select a previous or the next solution to update current solution)
  • in-significant: The results will not much different (because the selecting process - select a random solution in population to update the current solution)

• Performance (Personal Opinion):

  • good: working good with benchmark functions (convergence good)
  • not good: not working good with benchmark functions (convergence not good, not balance the exploration and exploitation phase)

• Paras: The number of parameters in the algorithm (Not counting the fixed parameters in the original paper)

  • Almost algorithms have 2 paras (epoch, population_size) and plus some paras depend on each algorithm.
  • Some algorithms belong to "good" performance and have only 2 paras meaning the algorithms are outstanding

• Difficulty - Difficulty Level (Personal Opinion): Objective observation from author. Depend on the number of parameters, number of equations, the original ideas, time spend for coding, source lines of code (SLOC).

  • Easy: A few paras, few equations, SLOC very short
  • Medium: more equations than Easy level, SLOC longer than Easy level
  • Hard: Lots of equations, SLOC longer than Medium level, the paper hard to read.
  • Hard* - Very hard: Lots of equations, SLOC too long, the paper is very hard to read.

** For newbie, I recommend to read the paper of algorithms which difficulty is "easy" or "medium" difficulty level.
