Perhaps you should try some spelling variations:
"modified allocation optimization algorithms" » "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified location optimization algorithms"
"modified study solution algorithm" » "modified study evolution algorithm", "modified study convolution algorithms", "modified study evolutionary algorithm", "modified student solutions algorithm", "modified study evaluation 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 study solution algorithm") OR ("modified allocation optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified study solution algorithm ) or ( modified allocation optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified study solution algorithm") or ("modified allocation optimization algorithms"))*.
