Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified network » certified network, defined network, modified near
modified optimal » modified thermal

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

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