What is grenade explosion method/algorithm?

Hello, I am Shafiyana, final year student in Engineering Manufacturing . For my final year project, I have decided to do a study on the solving the optimization problem using Bees Algorithm. Thus, I would like to do a comparison between Artificial Bee Colony with Bees Algorithm inspired by grenade explosion method. I hope you can help me to clarify more about the advantages of using this method. Besides, I am also in search of the pseudo code for this grenade explosion method to further the progress of this research study. It would be a great help if you can assist me with my research study regarding this topic. Regards, Thank you.
