Perhaps you should try some spelling variations:
optimization algorithmssssss » optimization algorithms
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
same optimization » game optimization, stage optimization, qoe optimization

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( parameters optimisation algorithm ) OR ( same optimization algorithmssssss ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( parameters optimisation algorithm ) OR ( same optimization algorithmssssss ))".
• Adding a wildcard symbol may retrieve word variants: (( parameters optimisation algorithm ) OR ( same optimization algorithmssssss ))*.
