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