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