what is the Recent Nature Inspired Algorithm for Optimization? I'm into designing a recommender system for movie database and for effective optimization.I suggested the idea of using particle swamp optimization ,but my professors need recent algorithms,can any one suggest recent nature inspired algorithms for optimization.(After Cuckoo Search Optimization).
This paper[[1]] recommends the following Swarm Intelligence algorithms:


  
  Ant colony optimization
  Bat algorithm
  Cuckoo search
  Firefly algorithm
  Particle swarm optimization
