Perhaps you should try some spelling variations:
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"
"modified game estimation algorithmss" » "modified game estimation algorithms", "modified game estimation algorithm", "modified game optimization algorithms", "modified pose estimation algorithmss", "modified game optimization algorithmss", "modified male estimation algorithmss", "modified adam estimation algorithmss"

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 parameter optimization algorithm") OR ("modified game estimation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified parameter optimization algorithm ) or ( modified game estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimization algorithm") or ("modified game estimation algorithmss"))*.
