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