Perhaps you should try some spelling variations:
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization algorithm"
"modified static optimized algorithms" » "modified static optimized algorithm", "modified static optimizer algorithms", "modified static optimization 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 network optimization algorithm") or ("modified static optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimization algorithm") OR ("modified static optimized algorithms")).
• Removing quotes may allow a broader search: (( modified network optimization algorithm ) or ( modified static optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithm") or ("modified static optimized algorithms"))*.
