DETROIT - Honda is recalling nearly 205,000 minivans and SUVs in the U.S.
and Canada to fix a problem with the automatic shifters.
The recall includes the Honda CR-V small SUV and Odyssey minivan from the
2012 and 2013 model years. Also covered is the 2013 Acura RDX SUV.
Honda says the device that stops drivers from shifting out of park without a
foot on the brake may not work properly. The problem occurs in below-
freezing temperatures.

做下面的（3）。
3. The others you should prove on your own, as essential exercises

我按照普通娃的特点修改一下（3）：对于普通娃而言，至少是试图自己先 work

I have no network problem between my laptop and the server.
Furthermore, I can telnet the server port 3389, the same server can be

It is not a big problem. The rigorous math behind that is
the equality holds for values of |x| < 1, hence the two
sides must
be equal as _rational polynomials_ (which makes convergence
not a problem). You can multiply all the
denominators and convert the problem to equality in
polynomials
to avoid using poles.

Actually I also mentioned this in my second point. What you are saying
is try to find the NLP relaxation for the original integer programming
problem, I think. But even if the relaxation can be solved easily, it is generally
still very difficult to get the real integer optimal or sub-optimal solution
solutions. That's why combinatorial problems are so hard, though it is only
