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)
"elements custom algorithm" » "elements fusion algorithm" (Expand Search), "elements control algorithm" (Expand Search), "elements lasso algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level routing algorithm" (Expand Search), "level according algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level using 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 custom algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modeling algorithm\") OR (\"elements custom algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( data modeling algorithm ) OR ( elements custom algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data modeling algorithm") OR ("elements custom algorithm"))) OR ("level coding algorithm"))*.
