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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("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"))*.
