Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
parameter estimation » parameter estimates, parameter optimization
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
game solution » time solutions, water solution, nacl solution
during game » during times, during waste

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

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