Perhaps you should try some spelling variations:
"modified network optimization algorithms" » "modified network optimisation algorithm", "modified network estimation algorithms", "modified network estimation algorithm", "certified network optimization algorithms", "defined network optimization algorithms", "modified near optimization algorithms"
"modified model predicting algorithm" » "modified model predation algorithm", "modified model predators algorithm", "modified model splitting algorithm", "modified model predictive algorithm", "modified model reduction algorithm", "modified male predicting algorithm"

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