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