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