Perhaps you should try some spelling variations:
"kantis colony optimization algorithm" » "santis colony optimization algorithm" (Expand Search), "kantis colon optimization algorithm" (Expand Search), "kantis colony optimizacion algorithm" (Expand Search), "kantis colony optimization algoritmo" (Expand Search), "kanteis colony optimization algorithm" (Expand Search), "kantiis colony optimization algorithm" (Expand Search), "kkantis 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("kantis colony optimization algorithm") OR ("ant colony optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"kantis colony optimization algorithm\") OR (\"ant colony optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( kantis colony optimization algorithm ) OR ( ant colony optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("kantis colony optimization algorithm") OR ("ant colony optimisation algorithm"))*.
