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