Perhaps you should try some spelling variations:
"a colon optimisation algorithm" » "a colon optimization algorithm" (Expand Search), "a colony optimisation algorithm" (Expand Search), "a colony optimization algorithm" (Expand Search), "a wolf optimisation algorithm" (Expand Search), "de colon optimisation algorithm" (Expand Search), "a common optimisation algorithm" (Expand Search), "el colon optimisation algorithm" (Expand Search)
"ant colon optimisation algorithm" » "ant colon optimization algorithm" (Expand Search), "ant colony optimisation algorithm" (Expand Search), "ant colony optimization algorithm" (Expand Search), "ant wolf optimisation algorithm" (Expand Search)

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