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