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