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