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 novel algorithm" » "element forest algorithm" (Expand Search), "element model algorithm" (Expand Search), "element ore algorithm" (Expand Search), "elements over algorithm" (Expand Search)
"elements fe algorithm" » "elements new algorithm" (Expand Search), "elements de algorithms" (Expand Search), "elements seu algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "element te algorithm" (Expand Search), "elements b 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 novel algorithm") OR ("elements fe algorithm"))) OR ("effects modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element novel algorithm\") OR (\"elements fe algorithm\"))) OR (\"effects modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element novel algorithm ) OR ( elements fe algorithm ))) OR ( effects modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element novel algorithm") OR ("elements fe algorithm"))) OR ("effects modeling algorithm"))*.
