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

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