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

Try widening your search to All Fields.

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 evolution algorithm") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified nodal evolution algorithm") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( modified nodal evolution algorithm ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified nodal evolution algorithm") or ("modified multiobjective optimization algorithm"))*.
