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)
ant colon » ant colony (Expand Search), a colon (Expand Search)
a colony » a colon (Expand Search), ant colony (Expand Search)

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

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