Perhaps you should try some spelling variations:
"a common optimisation algorithm" » "a common optimization algorithm" (Expand Search), "a colony optimisation algorithm" (Expand Search), "a colony optimization algorithm" (Expand Search), "a cooling optimization algorithm" (Expand Search), "_ common optimisation algorithm" (Expand Search), "a 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), "a colon optimisation algorithm" (Expand Search)

Try widening your search to All Fields.

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

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