Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"boiler using method algorithm" » "boiler using mom algorithm", "powder using method algorithm", "boiler nursing methods algorithm", "boiler focusing method algorithm", "boiler using metal 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 method algorithm\") OR (\"modified notion optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( boiler using method algorithm ) OR ( modified notion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("boiler using method algorithm") OR ("modified notion optimization algorithms"))*.
