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

You may be able to get more results by adjusting your search query.

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