better than the source, the source is replaced by the new solution. All the onlookers do
similar work to explore new solutions for the sources.
In ABC algorithm, if a position cannot be improved through a predetermined
number of cycles, which called limit , that food source has to be abandoned. Then the
employed bee related to that position becomes a scout and searches a new food source
randomly to replace the old one.
Above are the search processes of employed bees, onlookers, and scouts. The
framework of ABC algorithm is described in Fig. 1.
