Perhaps you should try some spelling variations:
"binary _ process optimization algorithm" » "binary _ model optimization algorithm" (Expand Search)
"binary based field optimization algorithm" » "binary based lead optimization algorithm" (Expand Search), "binary based guided optimization algorithm" (Expand Search), "binary based linear optimization algorithm" (Expand Search), "library based field optimization algorithm" (Expand Search), "linac based field optimization algorithm" (Expand Search), "binary mask field optimization algorithm" (Expand Search), "binary pulsed field optimization algorithm" (Expand Search)

Try widening your search to All Fields.

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

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