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 method algorithm" » "boiler learning mom algorithm", "mobile learning method algorithm", "boiler learning methods algorithm", "boiler graining methods algorithm", "boiler learning emotion algorithm"

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 method algorithm") or ("modified multiobjective optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("boiler learning method algorithm") OR ("modified multiobjective optimized algorithm"))*.
• Removing quotes may allow a broader search: (( boiler learning method algorithm ) or ( modified multiobjective optimized algorithm ))*.
