Perhaps you should try some spelling variations:
"data modeling algorithm" » "data scheduling algorithm" (Expand Search), "data models algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search)
"prevalence data algorithms" » "prevalence years algorithms" (Expand Search)
"element jaya algorithm" » "elements jaya algorithm" (Expand Search), "element maya algorithm" (Expand Search), "element aya algorithm" (Expand Search), "element jana 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: (("data modeling algorithm") OR ((("element jaya algorithm") OR ("prevalence data algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"element jaya algorithm\") OR (\"prevalence data algorithms\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( element jaya algorithm ) OR ( prevalence data algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("element jaya algorithm") OR ("prevalence data algorithms"))))*.
