Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm", "modified multiobjective optimized algorithms"
"modified nodal estimation algorithms" » "modified nodal estimation algorithm", "modified nodal optimisation algorithm", "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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified nodal estimation algorithms") OR ("modified multiobjective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified nodal estimation algorithms\") OR (\"modified multiobjective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified nodal estimation algorithms ) OR ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified nodal estimation algorithms") OR ("modified multiobjective optimization algorithms"))*.
