Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified nodal evolution algorithm" » "modified nodal solution algorithm", "modified nodal evolutionary algorithm", "modified nodal convolution algorithms", "modified global evolution algorithm", "modified legal revolution algorithm", "modified adam evolution algorithm", "modified near evolution algorithm"

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 multiobjective optimization algorithms") OR ("modified nodal evolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) or ( modified nodal evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") or ("modified nodal evolution algorithm"))*.
