Perhaps you should try some spelling variations:
complexity application » complexity applications, complexity approximation, complex applications
based extensible » based extension, based extensions, based reversible
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, array sharing
array using » arrays using

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "complexity application based extensible ((array string) OR (((array using) OR (array arcing))))~".
• Adding a wildcard symbol may retrieve word variants: complexity application based extensible ((array string) OR (((array using) OR (array arcing))))*.
