Perhaps you should try some spelling variations:
"linac based cohort optimization algorithm" » "linac based motor optimization algorithm" (Expand Search), "linac based chimp optimization algorithm" (Expand Search), "lina based cohort optimization algorithm" (Expand Search)
"binary basic process optimization algorithm" » "binary batch process 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: (("linac based cohort optimization algorithm") OR ("binary basic process optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"linac based cohort optimization algorithm\") OR (\"binary basic process optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( linac based cohort optimization algorithm ) OR ( binary basic process optimization algorithm ))*.
