Perhaps you should try some spelling variations:
"binary also require optimization algorithm" » "binary also required optimization algorithm" (Expand Search), "binary also resource optimization algorithm" (Expand Search), "binary also feature optimization algorithm" (Expand Search)
"binary image based optimization algorithm" » "binary image whale 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 also require optimization algorithm") OR ("binary image based optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary also require optimization algorithm\") OR (\"binary image based optimization algorithm\"))".
• Removing quotes may allow a broader search: (( binary also require optimization algorithm ) OR ( binary image based optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("binary also require optimization algorithm") OR ("binary image based optimization algorithm"))*.
