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