A Integer Programming without a objective function is a decision problem, instead of an optimization problem. Although the computational complexity is the same for both of them, decision problem is faster to solve, for it only requires one feasible solution (rather than the optimal one). In case an optimal solution is not neccesary, and bounds are given for a feasible one, such formulation is helpful.

Being science

Is the thrill gone?

Test from thinkfree posting to blogger

It's cool to use thinkfree office, which is based on java applets, meaning you can use it on almost all platforms with (or without) a browser. I've been editing ppt with it, and it seems to be able to accomplish most frequent tasks perfectly. It mimics MS office graphic interface very well (at least GUI compatible). All in all, it's a cool service, for free (this I doubt).
