Perhaps you should try some spelling variations:
"effects modeling algorithm" » "effects scheduling algorithm" (Expand Search), "event modeling algorithm" (Expand Search)
"tested using algorithm" » "tested cosine algorithm" (Expand Search), "system using algorithm" (Expand Search)
"elements data algorithm" » "elements jaya algorithm" (Expand Search), "elements deer 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 data algorithm") OR ((("tested using algorithm") OR ("effects modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements data algorithm\") OR (((\"tested using algorithm\") OR (\"effects modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( elements data algorithm ) OR ((( tested using algorithm ) OR ( effects modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements data algorithm") OR ((("tested using algorithm") OR ("effects modeling algorithm"))))*.
