Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified exact evolutionary algorithm" » "modified exact evolution algorithm", "modified exact 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 multiobjective optimization algorithm") or ("modified exact evolutionary algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimization algorithm") OR ("modified exact evolutionary algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) or ( modified exact evolutionary algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") or ("modified exact evolutionary algorithm"))*.
