Perhaps you should try some spelling variations:
"modified network optimisation algorithmss" » "modified network optimisation algorithm", "modified network optimization algorithms", "modified network estimation algorithms", "modified network optimization algorithmss", "certified network optimisation algorithmss", "defined network optimisation algorithmss", "modified near optimisation algorithmss"
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"

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