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

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