Perhaps you should try some spelling variations:
"modified allocation optimization algorithms" » "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimisation algorithms", "modified allocation estimation algorithmss", "modified location optimization algorithms"
"modified game optimization algorithm" » "modified game optimisation algorithm", "modified game estimation algorithm", "modified game estimation algorithms", "modified stage optimization algorithm", "modified qoe optimization algorithm", "modified market optimization algorithm", "modified male optimization algorithm", "modified adam 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 game optimization algorithm") OR ("modified allocation optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified game optimization algorithm ) or ( modified allocation optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified game optimization algorithm") or ("modified allocation optimization algorithms"))*.
