Perhaps you should try some spelling variations:
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation algorithm"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("boiler using method algorithm") OR ("modified network optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"boiler using method algorithm\") OR (\"modified network optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( boiler using method algorithm ) OR ( modified network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("boiler using method algorithm") OR ("modified network optimisation algorithm"))*.
