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

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 optimisation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimisation algorithm") OR ("modified allocation optimisation algorithms"))*.
• Removing quotes may allow a broader search: (( modified parameter optimisation algorithm ) or ( modified allocation optimisation algorithms ))*.
