Perhaps you should try some spelling variations:
"modified bi1 optimization algorithm" » "modified bi1 optimization algorithms", "modified bi1 optimisation algorithm", "modified bi1 estimation algorithm", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified game optimization algorithm"
"powder using methods algorithm" » "powder nursing methods algorithm", "powder making methods algorithm", "powder counting methods algorithm", "code using methods algorithm", "boiler using methods algorithm", "model using methods algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("powder using methods algorithm") OR ("modified bi1 optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"powder using methods algorithm\") OR (\"modified bi1 optimization algorithm\"))".
• Removing quotes may allow a broader search: (( powder using methods algorithm ) OR ( modified bi1 optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("powder using methods algorithm") OR ("modified bi1 optimization algorithm"))*.
