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: "((\"Ant colony optimisation algorithm\") OR (\"ant colony optimization algoritmo\"))~".
• Removing quotes may allow a broader search: (( Ant colony optimisation algorithm ) OR ( ant colony optimization algoritmo ))~.
• Adding a wildcard symbol may retrieve word variants: (("Ant colony optimisation algorithm") OR ("ant colony optimization algoritmo"))*.
