Perhaps you should try some spelling variations:
"kwante colony optimization algorithm" » "kwante colon optimization algorithm" (Expand Search), "kwante colony optimizacion algorithm" (Expand Search), "kwante colony optimization algoritmo" (Expand Search), "kwantee colony optimization algorithm" (Expand Search), "kwantie colony optimization algorithm" (Expand Search), "kwkante 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: (("kwante colony optimization algorithm") OR ("ant colony optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"kwante colony optimization algorithm\") OR (\"ant colony optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( kwante colony optimization algorithm ) OR ( ant colony optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("kwante colony optimization algorithm") OR ("ant colony optimisation algorithm"))*.
