Perhaps you should try some spelling variations:
"binary space bayesian optimization algorithm" » "binary space based optimization algorithm" (Expand Search)
"binary class data optimization algorithm" » "binary class dog optimization algorithm" (Expand Search), "binary class swarm optimization algorithm" (Expand Search), "binary class 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 space bayesian optimization algorithm\") OR (\"binary class data optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary space bayesian optimization algorithm ) OR ( binary class data optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary space bayesian optimization algorithm") OR ("binary class data optimization algorithm"))*.
