Hello all

I am trying to find the logical alan turing explanation why there can't be a program that checks another programs.

I remember we learned in on the computation course but now i just can't find the solution , and i need to explain it to some one at my work .

Thanks for help.

Hi, I have a question about turing machines and halting problem.

I'm working on a project for a Turning machine but having problems conceptualizing the steps. f(x) = x^3, where x is a single digit between 0 - 9 inclusive.

Turing Model Vs Von Neuman model

as seen on Stack Overflow - Search for 'Stack Overflow'
First some background (based on my understanding).. The Von-Neumann architecture describes the stored-program computer where instructions and data are stored in memory and the machine works by changing it's internal state, i.e an instruction operated on some data and modifies the data. So inherently… >>> More

Is there a "good enough" solution for the halting problem?

as seen on Stack Overflow - Search for 'Stack Overflow'
It is known that the halting problem cannot have a definite solution, one that a) returns true <== the program does indeed halt, and b) handles any input, but I was wondering if there are good enough solutions to the problem, ones that can maybe handle certain types of program flows perfectly,… >>> More
Practical non-Turing-complete languages?

as seen on Stack Overflow - Search for 'Stack Overflow'
Nearly all programming languages used are Turing Complete, and while this affords the language to represent any computable algorithm, it also comes with its own set of problems.
