Perhaps you should try some spelling variations:
"based modeling algorithm" » "based making algorithm" (Expand Search), "based model algorithm" (Expand Search), "based models algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"elements ipca algorithm" » "elements wgcna algorithm" (Expand Search), "elements cscap algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements crcy algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements ices 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: (((("elements ipca algorithm") OR ("element method algorithm"))) OR ("based modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements ipca algorithm\") OR (\"element method algorithm\"))) OR (\"based modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements ipca algorithm ) OR ( element method algorithm ))) OR ( based modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements ipca algorithm") OR ("element method algorithm"))) OR ("based modeling algorithm"))*.
