Chaitin s algorithm is a bottom up, graph coloring register allocation algorithm that uses cost degree as its spill metric . It is named after its designer, GregoryChaitin . Chaitin s algorithm was the first register allocation algorithm that made use of coloring of the interference graph for both register allocations and spilling. Chaitin s algorithm was presented on the 1982 SIGPLAN Symposium on Compiler Construction, and published in the symposium proceedings. It was extension of an earlier 1981 paper on the use of graph coloring for register allocation. Chaitin s algorithm formed the basis of a large section of research into register allocators.

These numbers are formed from a construction due to GregoryChaitin . Although there are infinitely many halting probabilities, it is common to use the letter to refer to them as if there were only one. Because depends on the program encoding used, it is sometimes called Chaitin s construction instead of Chaitin s constant when not referring to any specific encoding. Each halting probability is a normal number normal and transcendental number transcendental real number which is not computable number computable , which means that there is no algorithm that enumerates its digits. Background The definition of a halting probability relies on the existence of prefix free universal computable functions. Such a function, intuitively, represents a programming language with the property that no valid program can be obtained as a proper extension of another valid program. Suppose that F is a partial function that takes one argument, a finite binary ... would basically search for counter examples and halt if one is found , knowing enough bits of Chaitin ... solvable, and therefore calculating any but the first few bits of Chaitin s constant is not possible ...
