Perhaps you should try some spelling variations:
"binary step process optimization algorithm" » "binary step model optimization algorithm" (Expand Search), "binary stem process optimization algorithm" (Expand Search)
"binary image guided optimization algorithm" » "binary image based optimization algorithm" (Expand Search), "binary image model optimization algorithm" (Expand Search)

Try widening your search to All Fields.

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 guided optimization algorithm") OR ("binary step process optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary image guided optimization algorithm\") OR (\"binary step process optimization algorithm\"))".
• Removing quotes may allow a broader search: (( binary image guided optimization algorithm ) OR ( binary step process optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("binary image guided optimization algorithm") OR ("binary step process optimization algorithm"))*.
