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)
"gmm clustering algorithm" » "_ clustering algorithm" (Expand Search)
"element pso algorithm" » "element lasso algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "elements ppm 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 ("gmm clustering algorithm"))) OR ("element pso algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modeling algorithm\") OR (\"gmm clustering algorithm\"))) OR (\"element pso algorithm\"))".
• Removing quotes may allow a broader search: (((( data modeling algorithm ) OR ( gmm clustering algorithm ))) OR ( element pso algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data modeling algorithm") OR ("gmm clustering algorithm"))) OR ("element pso algorithm"))*.
