Perhaps you should try some spelling variations:
"primary data task optimization algorithm" » "primary data based optimization algorithm" (Expand Search), "primary data hawks optimization algorithm" (Expand Search), "primary data swarm optimization algorithm" (Expand Search)
"binary basic robust optimization algorithm" » "binary basis robust 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 basic robust optimization algorithm") OR ("primary data task optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary basic robust optimization algorithm\") OR (\"primary data task optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( binary basic robust optimization algorithm ) OR ( primary data task optimization algorithm ))*.
