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