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