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