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