Default P13 Question

The problem wording is to find the runs that are not linearly separable with a hard margin SVM. The expectation is that there are some.

Using LIBSVM with C=10^6, Ein is always 0; svmpredict is always 100%. The number of support vectors varies between 6 and 12, mode and median are 8.

Based on the question I was expecting some to be linearly inseparable. I increased the noise level (from .25 to 5.0). Still solved everyone, although the number of support vectors went up.

I tried 1000 points instead of 100. Eout soared, but Ein didn't budge.
