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