Perhaps you should try some spelling variations:
"modified nodal optimization algorithms" » "modified nodal optimisation algorithm", "modified nodal estimation algorithm", "modified nodal optimized algorithms", "modified global optimization algorithms", "modified qoe optimization algorithms", "modified adam optimization algorithms", "modified near optimization algorithms"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimisation algorithm", "modified objective approximation algorithms", "modified objective optimization algorithms", "modified objective allocation 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 optimization algorithms") OR ("modified objective estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified nodal optimization algorithms\") OR (\"modified objective estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified nodal optimization algorithms ) OR ( modified objective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified nodal optimization algorithms") OR ("modified objective estimation algorithms"))*.
