Perhaps you should try some spelling variations:
optimisation algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
sphere optimisation » sphere estimation
market optimization » game optimization, parameter optimization, market capitalization

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: "(( sphere optimisation algorithms ) OR ( market optimization algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( sphere optimisation algorithms ) OR ( market optimization algorithms ))*.
