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 deep evolution algorithm" » "modified deep solution algorithm", "modified deep evolutionary algorithm", "modified deep convolution algorithms", "modified delphi evolution algorithm", "modified df evolution algorithm", "modified near evolution 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 deep evolution algorithm") OR ("modified allocation optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified deep evolution algorithm ) or ( modified allocation optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified deep evolution algorithm") or ("modified allocation optimization algorithms"))*.
