Perhaps you should try some spelling variations:
"anti colony optimisation algorithm" » "anti colony optimization algorithm" (Expand Search), "ant colony optimisation algorithm" (Expand Search)
"ant colon optimisation algorithm" » "ant colon optimization algorithm" (Expand Search), "ant colony optimization algorithm" (Expand Search), "ant wolf optimisation algorithm" (Expand Search), "ant cooling optimization algorithm" (Expand Search), "ant colony optimisation algorithm" (Expand Search), "a colon optimisation 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: "((\"anti colony optimisation algorithm\") OR (\"ant colon optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( anti colony optimisation algorithm ) OR ( ant colon optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("anti colony optimisation algorithm") OR ("ant colon optimisation algorithm"))*.
