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