Perhaps you should try some spelling variations:
"effects sampling algorithm" » "effects making algorithm" (Expand Search), "effects modeling algorithm" (Expand Search), "effects mining algorithm" (Expand Search), "effects along algorithm" (Expand Search), "effects arising algorithm" (Expand Search)
"levels sorting algorithms" » "levels routing algorithm" (Expand Search), "levels learning algorithms" (Expand Search), "levels during algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement 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 data algorithm") OR ((("effects sampling algorithm") OR ("levels sorting algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element data algorithm\") OR (((\"effects sampling algorithm\") OR (\"levels sorting algorithms\"))))".
• Removing quotes may allow a broader search: (( element data algorithm ) OR ((( effects sampling algorithm ) OR ( levels sorting algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element data algorithm") OR ((("effects sampling algorithm") OR ("levels sorting algorithms"))))*.
