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