The chance of searching better condition for employed bees means that if employed bees failed to gain better solution after 100 times consecutively, it will leave its pattern and become a scout bee
to search another pattern.
(4) Scout bee
phase: If the food source [x.sub.i] cannot be improved through the limitation number of trails (limit), then generate a new position for [x.sub.i] by using (1).
phase: In this phase, the abandon counter with maximum content was matched with pre-defined limit value.
The scout bees
after returning from the search of food particle report about the quality of the food site by communication mode called waggle dance.
Random solutions were created during the scout bees
The rest of all the procedures after the onlooker bees and scout bees
phases follow the same steps as conventional ABC.
Initially, scout bees
identify the positions of all food sources.
In addition, if scout bees
leaving the swarm are unable to find a suitable nesting site, the swarm may start construction of their combs on a structure on which they have clustered, even though this would not be optimal for the colony on a ship.
Scout Phase: If the profitability of food source cannot be improved and the times of unchanged greater than the predetermined number of trials, which called "limit" and specified by the user of the ABC algorithm, the solutions will be abandoned by scout bees
. Then, the scouts start to randomly search the new solutions.
In this paper, we analyzed the peculiar control parameters of the ABC algorithm by the different limit values, number of scout bees
and population size.
provides another advantage, consisting in that if the method fails to find an object different from the others objects in the original solution, this means that the two solutions are equal, such situation is called "collision" and it is resolved by making the employed bee associated with the original solution, a scout bee
Three bee types are considered in ABC: employed, onlooker, and scout bees
. The employed bees are equal in number to the number of food sources with an employed bee being assigned to each food source.
