Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective solution » objective evolutionary, objective allocation
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
pulse optimization » policy optimization, game optimization, qoe optimization
modified pulse » modified male, modified passive

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 objective solution algorithm ) OR ( modified pulse optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified objective solution algorithm ) or ( modified pulse optimization algorithms ))*.
