Perhaps you should try some spelling variations:
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"
"modified total optimized algorithms" » "modified total optimized algorithm", "modified total optimizer algorithms", "modified total optimization algorithms", "modified thermal optimized algorithms", "modified ti6al4v optimized 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 objective allocation algorithm") OR ("modified total optimized algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective allocation algorithm ) or ( modified total optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithm") or ("modified total optimized algorithms"))*.
