130 C JJV added checker to see if log(alpha/(b+w)) will |
| 3188 | 131 C JJV overflow. If so, we count the log as -INF, and |
| 132 C JJV consequently evaluate conditional as true, i.e. | |
| 133 C JJV the algorithm rejects the trial and starts over | |
| 134 C JJV May not need this here since ALPHA > 2.0 | |
