WebThere are many existing encoding methods, such as Direct Encoding (DE), Histogram Encoding (HE), Unary Encoding (UE), Binary Local Hashing (BLH), etc. In this paper, use optimized unary encoding (Optimized Unary Encoding, OUE), which is an optimized scheme of binary encoding. Compared with other encoding schemes, OUE has a smaller variance. WebFor example, I installed a build of Subversion from source to /usr/local, then typed svnsync help at the Bash prompt.
