Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"boiler using real algorithm" » "boiler using adam algorithm", "boiler using search algorithm", "powder using real algorithm", "boiler using metal algorithm", "boiler using raw 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 using real algorithm\") OR (\"modified multiobjective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( boiler using real algorithm ) OR ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("boiler using real algorithm") OR ("modified multiobjective optimisation algorithm"))*.
