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