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 orca solution algorithm" » "modified orca evolution algorithm", "modified orca convolution algorithms", "modified orca evolutionary algorithm", "modified norway solution algorithm", "modified drug solution algorithm", "modified nacl solution algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified orca solution algorithm") or ("modified allocation estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified orca solution algorithm") OR ("modified allocation estimation algorithms")).
• Removing quotes may allow a broader search: (( modified orca solution algorithm ) or ( modified allocation estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified orca solution algorithm") or ("modified allocation estimation algorithms"))*.
