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