Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
evolution algorithm » evolutionary algorithm, convolution algorithms, estimation algorithm
solution algorithm » convolution algorithms, evolutionary algorithm, estimation algorithm
differential » different

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

• Performing a fuzzy search may retrieve terms with similar spellings: differential ((optimisation algorithm) or (((evolution algorithm) or (solution algorithm))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: differential ((optimisation algorithm) OR (((evolution algorithm) OR (solution algorithm)))).
• Adding a wildcard symbol may retrieve word variants: differential ((optimisation algorithm) or (((evolution algorithm) or (solution algorithm))))*.
