Perhaps you should try some spelling variations:
"binary task policy optimization algorithms" » "binary task capacity optimization algorithms" (Expand Search)
"binary mass based optimization algorithm" » "binary images 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 mass based optimization algorithm") OR ("binary task policy optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary mass based optimization algorithm\") OR (\"binary task policy optimization algorithms\"))*".
• Removing quotes may allow a broader search: (( binary mass based optimization algorithm ) OR ( binary task policy optimization algorithms ))*.
