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