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