Perhaps you should try some spelling variations:
"modified nodal estimation algorithmss" » "modified nodal estimation algorithms", "modified nodal estimation algorithm", "modified nodal optimization algorithms", "modified pose estimation algorithmss", "modified adam estimation algorithmss", "modified near estimation algorithmss"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified nodal estimation algorithmss") or ("modified objective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified nodal estimation algorithmss") OR ("modified objective optimization algorithm")).
• Removing quotes may allow a broader search: (( modified nodal estimation algorithmss ) or ( modified objective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified nodal estimation algorithmss") or ("modified objective optimization algorithm"))*.
