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

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

• Removing quotes may allow a broader search: (( ant colony optimisation algorithm ) OR ( a colon optimisation algorithm )).
