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