Perhaps you should try some spelling variations:
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"model nine algorithms" » "model five algorithms" (Expand Search), "model tree algorithms" (Expand Search), "model based algorithms" (Expand Search), "model fine algorithms" (Expand Search), "model note algorithms" (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 method algorithm") OR ("model nine algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithm\") OR (\"model nine algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithm ) OR ( model nine algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithm") OR ("model nine algorithms"))) OR ("neural coding algorithm"))*.
