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