Perhaps you should try some spelling variations:
"modified allocation optimization algorithm" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified location optimization algorithm"
"modified passive solution algorithms" » "modified passive solution algorithm", "modified passive evolution algorithm", "modified passive convolution algorithms", "modified adaptive solution algorithms", "modified positive solutions algorithms", "modified saline solution algorithms"

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 allocation optimization algorithm") OR ("modified passive solution algorithms"))~.
• Removing quotes may allow a broader search: (( modified allocation optimization algorithm ) or ( modified passive solution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithm") or ("modified passive solution algorithms"))*.
