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 algorithm"
"modified nodal estimation algorithms" » "modified nodal estimation algorithm", "modified nodal optimization algorithms", "modified nodal approximation algorithms", "modified pose estimation algorithms", "modified adam estimation algorithms", "modified near estimation 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 nodal estimation algorithms") OR ("modified multiobjective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified nodal estimation algorithms ) or ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified nodal estimation algorithms") or ("modified multiobjective optimisation algorithm"))*.
