Perhaps you should try some spelling variations:
optimization algorithms » estimation algorithms, estimation algorithm, optimized algorithms
optimisation algorithm » estimation algorithm, estimation algorithms
male optimisation » game optimization, market optimization, stage optimization
df optimization » _ optimization, qoe optimization, _ optimisation
modified df » modified _, modified adam, modified bi1

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified df optimization algorithms ) OR ( modified male optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified df optimization algorithms ) or ( modified male optimisation algorithm ))*.
