Perhaps you should try some spelling variations:
"binary tasks based optimization algorithm" » "binary states based optimization algorithm" (Expand Search)
"binary gaps swarm optimization algorithm" » "binary gas swarm optimization algorithm" (Expand Search), "binary gap 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 tasks based optimization algorithm\") OR (\"binary gaps swarm optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary tasks based optimization algorithm ) OR ( binary gaps swarm optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary tasks based optimization algorithm") OR ("binary gaps swarm optimization algorithm"))*.
