Perhaps you should try some spelling variations:
"experiments using algorithms" » "experiments show algorithms" (Expand Search), "experimental testing algorithms" (Expand Search), "experiments pacing algorithms" (Expand Search), "experiments nine algorithms" (Expand Search), "experiments sorting algorithms" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"elements res algorithm" » "elements best algorithm" (Expand Search), "elements rast algorithm" (Expand Search), "elements new algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements mges 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 res algorithm") OR ("experiments using algorithms"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements res algorithm\") OR (\"experiments using algorithms\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements res algorithm ) OR ( experiments using algorithms ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements res algorithm") OR ("experiments using algorithms"))) OR ("level coding algorithm"))*.
