600.103 Solutions to Homework #1 Kenneth.Church@jhu.edu
Newton’s Method • x1 > 0 2 • x1 < 0 -2 • x1 = 0 NaN
R & Fib • F(15)=610
Halting Problem • What does this have to do with computability? • The Halting Problem demonstrates that you cannot compute everything • In other words, the set of all computable functions is a proper subset of the set of all functions
