Here are the test outputs. They do not seem to iterate at all (whereas
./example does). What is the expected output of example?

g50.out
Graph is of size 50 103
Iter:  0 Ap: 0.00e+00 Pobj:  1.0355339e+04 Ad: 0.00e+00 Dobj:
 0.0000000e+00
Too many line search failures, giving up.
Failure: return code is 9
Primal objective value: 1.0355339e+04
Dual objective value: 0.0000000e+00
Relative primal infeasibility: 5.18e+03
Relative dual infeasibility: 1.02e+01
Real Relative Gap: -1.00e+00
XZ Relative Gap: 7.21e+01
DIMACS error measures: 5.18e+03 0.00e+00 2.60e+02 0.00e+00 -1.00e+00
7.21e+01

Theta1.out
