Perhaps you should try some spelling variations:
"modified affects digitization algorithms" » "modified affects optimization algorithms", "modified affects estimation algorithms", "modified effects digitization algorithms", "modified affect digitization algorithms", "modified affected digitization algorithms"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation 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 affects digitization algorithms") OR ("modified objective allocation algorithm"))~.
• Removing quotes may allow a broader search: (( modified affects digitization algorithms ) or ( modified objective allocation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified affects digitization algorithms") or ("modified objective allocation algorithm"))*.
