Perhaps you should try some spelling variations:
"binary class weight optimization algorithm" » "binary class igdt optimization algorithm" (Expand Search)
"binary cracks based optimization algorithm" » "binary crack based optimization algorithm" (Expand Search)

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

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