解决停机问题
Getting around the Halting Problem
摘要:
存在数k和s以及满足以下条件的URM程序A(n,m)。1.如果A(n,m)停止,则Cn(m)发散。2.对所有n,C_k(n)= A(n,n),C_s(n)= C_k(s). 3. A(k,s)停止,对于所有n,A(s,n)发散。这里C_n(_)是一个索引为n的程序,它是对所有可能程序的穷举。这对解决说谎者悖论和将哥德尔不完备性定理推广到PA以外的形式系统具有意义。
英文摘要:
There are numbers k and s and a URM program A(n,m) satisfying the following conditions. 1. If A(n,m) halts, then Cn(m) diverges. 2. For all n, C_k(n) = A(n,n) and C_s(n) = C_k(s). 3. A(k,s) halts and for all n, A(s,n) diverges. Here C_n(_) is a program with index n in some exhaustive enumeration of all possible programs. This has implications for solving the liar paradox and for generalization of Gödel incompleteness theorem to formal systems other than PA.
