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