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

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 made optimizer algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified network optimization algorithm ) OR ( modified made optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified network optimization algorithm ) or ( modified made optimizer algorithms ))*.
