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