Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified global solutions algorithm" » "modified global solution algorithm", "modified global evolution algorithm", "modified global evolutionary algorithm", "modified model solutions algorithm", "modified nodal solution algorithm"

You may be able to get more results by adjusting your search query.

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