Perhaps you should try some spelling variations:
"modified sphere optimisation algorithm" » "modified sphere optimization algorithms", "modified sphere estimation algorithm", "modified sphere estimation algorithms"
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter estimation algorithm", "modified parameter estimation algorithms", "modified parameters 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 sphere optimisation algorithm") OR ("modified parameter optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified sphere optimisation algorithm ) or ( modified parameter optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified sphere optimisation algorithm") or ("modified parameter optimization algorithm"))*.
