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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"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 ))~.
• Adding a wildcard symbol may retrieve word variants: (("boiler learning method algorithm") OR ("modified multiobjective optimized algorithm"))*.
