Perhaps you should try some spelling variations:
"effects modeling algorithm" » "effects making algorithm" (Expand Search), "effects model algorithm" (Expand Search), "effects models algorithm" (Expand Search), "effect model algorithm" (Expand Search)
"effect testing algorithm" » "effect twisting algorithm" (Expand Search), "effect hastings algorithm" (Expand Search), "effect boosting algorithm" (Expand Search), "effect test algorithm" (Expand Search), "effect tests algorithm" (Expand Search), "effect using algorithm" (Expand Search)
"elements em algorithm" » "elements new algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements res 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 em algorithm") OR ((("effects modeling algorithm") OR ("effect testing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements em algorithm\") OR (((\"effects modeling algorithm\") OR (\"effect testing algorithm\"))))".
• Removing quotes may allow a broader search: (( elements em algorithm ) OR ((( effects modeling algorithm ) OR ( effect testing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements em algorithm") OR ((("effects modeling algorithm") OR ("effect testing algorithm"))))*.
