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

You may be able to get more results by adjusting your search query.

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