Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, optimized algorithms
allocation estimation » allocation optimization, motion estimation
based optimization » game optimization, market optimization, qoe optimization
modified based » modified male

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: "(( modified based optimization algorithms ) OR ( modified allocation estimation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified based optimization algorithms ) OR ( modified allocation estimation algorithm ))*.
