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"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"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"))*.
