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