Perhaps you should try some spelling variations:
"modified allocation estimation algorithm" » "modified allocation optimization algorithm", "modified motion estimation algorithm"
"verified network optimized algorithm" » "verified network optimized algorithms", "verified network optimizer algorithms", "verified network optimization algorithm", "certified network optimized algorithm", "defined network optimized 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 algorithm") OR ("verified network optimized algorithm"))~.
• Removing quotes may allow a broader search: (( modified allocation estimation algorithm ) or ( verified network optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation estimation algorithm") or ("verified network optimized algorithm"))*.
