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