Perhaps you should try some spelling variations:
"element tracking algorithm" » "element learning algorithm" (Expand Search), "element processing algorithm" (Expand Search), "movement tracking algorithm" (Expand Search), "sleep tracking algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"effects models algorithm" » "effects modeling algorithm" (Expand Search), "effects novel algorithm" (Expand Search), "effects forest algorithm" (Expand Search), "effects model algorithm" (Expand Search)
"effects modbo algorithm" » "effects model algorithm" (Expand Search), "effect model algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("element tracking algorithm") OR ((("effects models algorithm") OR ("effects modbo algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element tracking algorithm\") OR (((\"effects models algorithm\") OR (\"effects modbo algorithm\"))))".
• Removing quotes may allow a broader search: (( element tracking algorithm ) OR ((( effects models algorithm ) OR ( effects modbo algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element tracking algorithm") OR ((("effects models algorithm") OR ("effects modbo algorithm"))))*.
