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