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"
"modified passive solution algorithm" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive evolutionary algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm", "modified saline solution algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bi1 optimization algorithm") OR ("modified passive solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified bi1 optimization algorithm ) or ( modified passive solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bi1 optimization algorithm") or ("modified passive solution algorithm"))*.
