Bee Colony Selection

Fig. 5 represents the behavior of the bee colony forages. The bee colony is initially completely unaware of the food sources. In the current stage, the bee plays the role of a scout or a recruit and randomly searches for a food source. As long as the food source is located, the bee is employed bee for memorizing the nectar amount and also the locations of food sources. After returning to the hive, the bee discharges some nectar and dances rhythmically to attract the onlooker bees [26]. A rhythmic dance or the waggle dance provides three parts of data: (a) the angle of the straight part designates the direction of the food source, (b) the length of the straight part reveals the distance of the food source from the hive, and (c) the duration of the dance indicates the quality of the nectar (Fig. 6). During the evaluation of the nectar amount of the new food sources, both the employed bees and the onlooker ones continuously update their memory. When the nectar amount is insufficient, this location …show more content…
In other words, all the search processes provide all the solutions for the problems, so that the hardness of ceramic Al2O3–TiC–TiN samples either increases or decreases. The best search which leads to the best solution (the best food source), represents the best optimized values for the process parameters. Depending on the local or visual information, an employed bee generates an amendment to the position (solution) in its memory and tests the nectar amount (the fitness value) of the new food source (new solution). With the assumption that the nectar amount of the new source is more than that of the prior food source, the bee memorizes the new position and forgets the old one. Otherwise, it keeps the position of the previous source in its memory. When the search process is over, the employed bees completely share the nectar information and the food sources position information with the onlooker bees in the dance area
