Perhaps you should try some spelling variations:
"wanti colony optimization algorithm" » "anti colony optimization algorithm" (Expand Search), "want colony optimization algorithm" (Expand Search), "wants colony optimization algorithm" (Expand Search), "wanti colon optimization algorithm" (Expand Search), "wanti colony optimizacion algorithm" (Expand Search), "wanti colony optimization algoritmo" (Expand Search), "wantei colony optimization algorithm" (Expand Search), "wantii colony optimization algorithm" (Expand Search), "wkanti colony optimization algorithm" (Expand Search)
"ant colony optimisation algorithm" » "ant colon optimisation algorithm" (Expand Search), "ant colony optimisation algoritmo" (Expand Search), "ante colony optimisation algorithm" (Expand Search), "anti colony optimisation algorithm" (Expand Search), "kant colony optimisation algorithm" (Expand Search), "ant colony optimizacion 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: "((\"wanti colony optimization algorithm\") OR (\"ant colony optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( wanti colony optimization algorithm ) OR ( ant colony optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("wanti colony optimization algorithm") OR ("ant colony optimisation algorithm"))*.
