Perhaps you should try some spelling variations:
"binary gaps whale optimization algorithm" » "binary gaps swarm optimization algorithm" (Expand Search), "binary gas whale optimization algorithm" (Expand Search), "binary gap whale optimization algorithm" (Expand Search)
"binary states based optimization algorithm" » "binary strategy based optimization algorithm" (Expand Search), "binary systems based optimization algorithm" (Expand Search), "binary system based optimization algorithm" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("binary states based optimization algorithm") OR ("binary gaps whale optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary states based optimization algorithm\") OR (\"binary gaps whale optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( binary states based optimization algorithm ) OR ( binary gaps whale optimization algorithm ))*.
