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

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