Perhaps you should try some spelling variations:
"ant herding optimisation algorithm" » "ant picking optimisation algorithm" (Expand Search), "ant cooling optimization algorithm" (Expand Search), "ante herding optimisation algorithm" (Expand Search), "anti herding optimisation algorithm" (Expand Search), "kant herding optimisation algorithm" (Expand Search)
"a colony optimization algorithm" » "a colony optimisation algorithm" (Expand Search), "a colon optimization algorithm" (Expand Search), "ant colony 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: (("ant herding optimisation algorithm") OR ("a colony optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ant herding optimisation algorithm\") OR (\"a colony optimization algorithm\"))".
• Removing quotes may allow a broader search: (( ant herding optimisation algorithm ) OR ( a colony optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("ant herding optimisation algorithm") OR ("a colony optimization algorithm"))*.
