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

Try widening your search to All Fields.

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

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