Perhaps you should try some spelling variations:
"modified notion optimisation algorithmsss" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified network optimization algorithmsss"
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization algorithms"

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