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)
"develop pso algorithms" » "develop pso algorithm" (Expand Search), "develop two algorithms" (Expand Search), "develop ppo algorithm" (Expand Search), "develop post algorithms" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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: (((("develop pso algorithms") OR ("relevant data algorithm"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop pso algorithms\") OR (\"relevant data algorithm\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( develop pso algorithms ) OR ( relevant data algorithm ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop pso algorithms") OR ("relevant data algorithm"))) OR ("data modeling algorithm"))*.
