Hey,
I'm studying Rudin's Real and Complex Analysis by myself and it would be really nice
if I could find a solution manual to all/part of the exercises at the end of the chapters.
Does anyone know if such a solution manual exists?
Thanks
Suppose we have two finite abelian groups G,G^{\prime} of size n=pq, p,q being primes. G is cyclic.
Both G,G^{\prime} have subgroups H,H^{\prime}, both of size q. The factor groups G/H,\ G^{\prime}/H^{\prime} are cyclic and since they are of equal size, they are isomorphic. Are G,G^{\prime}...
Let A, M be a commutative ring and a finitely generated A-module respectively. Let \phi be an A-module endomorphism of M such that \phi (M)\subseteq \alpha\ M where \alpha is an ideal of A. Let x_1,\dots,x_n be the generators of M. Then we know that \displaystyle{\phi(x_i)=\sum_{j=1}^{n}...
Suppose we have a two giant ideal springs very far apart from each other such that each spring can be used to launch a spaceship X to relativistic speeds. So a spaceship is launched using spring A to relativistic speeds, it reaches spring B which it compresses and is thus relaunched when spring...
Is there an easy (by which I mean an algorithm polynomial in size of input) way to know whether in the multiplicative group of integers mod P (P is a prime), whether an element is a generator or not?
I'm not entirely clear on the concept of kolmogorov complexity. Does it mean that the a certain string is complex if there is no combinatorial (not sequential) circuit which outputs that string or does it mean that a certain string is complex if there is no program which can output that string...
Say you have two circuits C1 and C2, a circuit being a directed acyclic graph in which each node is a NAND gate or an input variable.
C1 and C2 represent the same boolean function B. The only operations allowed on C1 and C2 are adding a gate node (with edges to some other nodes) or removing...
Simplex is exponential in the worst-case. Although there's Karmarkar's algorithm, it is for optimization of an objective function. Although it can be used for solving systems of linear inequalities, it takes n^3.5*L^2 time. I was wondering if there was a faster algorithm for giving a solution to...
Hi,
Is there a polynomial time algorithm (polynomial time in terms of the number of input constraints and variables) to solve a system of linear inequalities or or indicate whether a solution for a system of linear inequalities exists or not?
Thanks
Thanks for the reply. I just need a true and false answer as to whether a path exists or not.
Unfortunately the adjacency matrix trick won't work because the adjacency matrix itself is
n^2 big (n being the number of nodes in the graph) making the whole operation atleast
O(n^2).
Is there an algorithm which is O(1) or O(log n) (basically a very fast algorithm) which can tell whether there is a path from a node A to a node B in a graph?
Thanks
Well there's galahad but it's in fortran

You can use it in C/C++ code though I believe.Also there's Ipopt for nonlinear optimization written in C++.

You might also want to check out Numerical Recipes in C
The book is available online...
