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