You may be able to get more results by adjusting your search query.

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