Perhaps you should try some spelling variations:
"data modelling algorithm" » "data modeling algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"gmm clustering algorithm" » "_ clustering algorithm" (Expand Search)
"element pass algorithm" » "element lasso algorithm" (Expand Search), "element pso algorithm" (Expand Search), "element rast algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 modelling algorithm") OR ("gmm clustering algorithm"))) OR ("element pass algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modelling algorithm\") OR (\"gmm clustering algorithm\"))) OR (\"element pass algorithm\"))".
• Removing quotes may allow a broader search: (((( data modelling algorithm ) OR ( gmm clustering algorithm ))) OR ( element pass algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data modelling algorithm") OR ("gmm clustering algorithm"))) OR ("element pass algorithm"))*.
