Perhaps you should try some spelling variations:
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element two algorithms" » "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element art algorithms" (Expand Search), "element te algorithms" (Expand Search)
"elements ppo algorithm" » "elements pso algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements upon 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 ((("elements ppo algorithm") OR ("element two algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"elements ppo algorithm\") OR (\"element two algorithms\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( elements ppo algorithm ) OR ( element two algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("elements ppo algorithm") OR ("element two algorithms"))))*.
