Comments on: Let the games begin - The Wiring Game, that is! http://blogs.mathworks.com/contest/2008/04/30/let-the-games-begin-the-wiring-game-that-is/ The MATLAB Programming Contest is a semi-annual competition where contestants submit MATLAB code to try to solve a challenge. For more information, see the overview.

Bridges can only be used for crossovers, they can't be used to have two 90 angles at the same coordinate. 2. You can not bridge pins, if I am not wrong you'll pay for them but they'll be ignored. 3. The example that described the cost of the bridge should give a net score of 25+3-(11*2) = 6 4. The size of the boards (as well as other parameters in the testsuite) are sampled from a distribution, therefore theoretically speaking there is no limit, but in practice you could expect that most likely the distributions of the board sizes wil resemble those in the sample testsuite. 5. "T" connections and "+" connections are possible and you do not pay extra but the number of wires used (3 and 4 respectively) 6. Darkness does not mean "do not answer questions", I'll be around for a while, let me know if you have questions. Good luck, P.S. As orginizer I get the chance to peek at some of your entries :), we have started receiving some interesting pieces of code. Lucio The MathWorks Contest Team Answers to some of your questions:

1. Bridges can only be used for crossovers, they can’t be
used to have two 90 angles at the same coordinate.
2. You can not bridge pins, if I am not wrong you’ll pay
for them but they’ll be ignored.
3. The example that described the cost of the bridge should
give a net score of 25+3-(11*2) = 6
4. The size of the boards (as well as other parameters in
the testsuite) are sampled from a distribution, therefore
theoretically speaking there is no limit, but in practice
you could expect that most likely the distributions of the
board sizes wil resemble those in the sample testsuite.
5. “T” connections and “+” connections are possible and you
do not pay extra but the number of wires used (3 and 4
respectively)
6. Darkness does not mean “do not answer questions”, I’ll be around for a while, let me know if you have questions.

Good luck,

In this diagram we've saved 22 points by connecting the two 11 pins, but we had to buy three connectors and a bridge, for a total cost of 28. The net score for this move is 17, making it a really bad move. Is the net scorce not 6? (-22+28) Bridges are expensive: they cost 25 points each.

The segments for the connector between the 8 pins could be written like so. w = [ 2 3 2 4 ] [ 2 4 3 4 ] [ 3 4 3 5 ] [ 3 5 4 5 ] [ 4 5 5 6 ] Shouldn’t the last line of this part of the instructions say [ 4 5 4 6] ?

The segments for the connector between the 8 pins could be written like so.
w = [ 2 3 2 4 ]
[ 2 4 3 4 ]
[ 3 4 3 5 ]
[ 3 5 4 5 ]
[ 4 5 5 6 ]
