Binary erasure channel erasure channel which shares many similar theoretical results with the binary erasure channel. The BEC is a "binary channel"; that is, it can transmit only one of two symbols (usually called 0 and 1). (A non-binary channel would be capable of transmitting more than two symbols, possibly even an infinite number of choices.) The channel is not perfect and sometimes the bit gets "erased"; that is, the bit gets scrambled so the receiver has no idea what the bit was. The BEC is, in a sense, error-free. Unlike the binary symmetric channel, when the receiver gets a bit, it is
Skew binary number system into a skew binary number runs in time linear in the length of the number. Skew binary numbers find applications in skew binomial heaps, a variant of binomial heaps that support worst-case O(1) insertion, and in skew binary random access lists, a purely functional data structure. They also find use in bootstrapped skew binomial heaps, which have excellent asymptotic guarantees. If smoothsort is implemented using perfect binary trees (rather than the more common Leonardo trees), the heap is divided into trees which correspond to the digits of the skew binary representation of the heap size.
