Perhaps you should try some spelling variations:
"binary mass guided optimization algorithm" » "binary mass based optimization algorithm" (Expand Search), "binary mass inspired optimization algorithm" (Expand Search)
"binary tasks spider optimization algorithm" » "binary tasks inspired optimization algorithm" (Expand Search), "binary task spider optimization algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

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