 # TSZ
 Error-bounded Lossy Data Compressor For Float Double 
+
+TSZ algorithm is come from SZ algorithm, Github url is  https://github.com/szcompressor .
+
+Bellow is aspect of improvement :
+  1) Better speed and size
+  
+     SZ head size about 24 bytes, we are reduced to 2 bytes.
+     we delete some no use code and some unnecessary function could be droped.
+  2) Support multi-threads, interface is thread-safety.
+  3) Remove 2D 3D 4D 5D function, only 1D be remained.
+  4) Remove int8 int16 int32 and other datatype, only float double be remained.
+  5) Optimize code speed
+  6) Other optimize...
+  
+After modify, TSZ become faster、smaller and independent.  TSZ more suitable for small block data compression.
