2...7 times less memory consumption compared to version 2.0 .

SymSpell v2.0

While the basic idea of the Symmetric Delete spelling correction algorithm remains unchanged the implementation has been significantly improved to unleash the full potential of the algorithm.

This results in a 10 times faster spelling correction and 5 times faster dictionary generation and a less memory consuming dictionary compared to version 1.6 .

Compared to Peter Norvig's algorithm it is now 1,000,000 times faster for edit distance=3 and 10,000 times faster for edit distance=2.

SymSpell v1.6
