Perhaps you should try some spelling variations:
"binary task chimp optimization algorithm" » "binary task whale optimization algorithm" (Expand Search)
"binary maps swarm optimization algorithm" » "binary mass swarm optimization algorithm" (Expand Search), "binary gaps swarm optimization algorithm" (Expand Search), "binary map swarm optimization algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary task chimp optimization algorithm\") OR (\"binary maps swarm optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary task chimp optimization algorithm ) OR ( binary maps swarm optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary task chimp optimization algorithm") OR ("binary maps swarm optimization algorithm"))*.
