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