Perhaps you should try some spelling variations:
"model testing algorithm" » "model twisting algorithm" (Expand Search), "model hastings algorithm" (Expand Search), "model boosting algorithm" (Expand Search), "model fitting algorithm" (Expand Search), "model test algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"elements cc3d algorithm" » "elements cscap algorithm" (Expand Search), "elements cnn algorithm" (Expand Search), "elements wold algorithm" (Expand Search), "elements crcy algorithm" (Expand Search), "elements ices algorithm" (Expand Search), "elements uce 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 cc3d algorithm") OR ("model testing algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements cc3d algorithm\") OR (\"model testing algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements cc3d algorithm ) OR ( model testing algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements cc3d algorithm") OR ("model testing algorithm"))) OR ("neural coding algorithm"))*.
