Perhaps you should try some spelling variations:
"binary levels based optimization algorithm" » "binary event based optimization algorithm" (Expand Search), "binary models based optimization algorithm" (Expand Search)
"binary values based optimization algorithm" » "binary value based optimization algorithm" (Expand Search)

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: "((\"binary values based optimization algorithm\") OR (\"binary levels based optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary values based optimization algorithm ) OR ( binary levels based optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary values based optimization algorithm") OR ("binary levels based optimization algorithm"))*.
