Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
network optimized » network optimization
modified network » certified network, defined network, modified near

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

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