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