Perhaps you should try some spelling variations:
"binary 2 whale optimization algorithm" » "binary 2 swarm optimization algorithm" (Expand Search), "binary 2 based optimization algorithm" (Expand Search)
"binary basic robust optimization algorithm" » "binary basis robust 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 2 whale optimization algorithm\") OR (\"binary basic robust optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary 2 whale optimization algorithm ) OR ( binary basic robust optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary 2 whale optimization algorithm") OR ("binary basic robust optimization algorithm"))*.
