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