See my previous post re your last program. Most of the comments are relevant for this post.
In particular, do not overwrite defaults unless you have a darned good reason.
Also, it is very seldom that a 2nd hidden layer is necessary.
Validation stopping was created to make sure the trained net is useful for nontraining data. Stopping after MSEval increases for 6 consecutive epochs is reasonable.
You will get different results every time because the initial weights are random.
For each different setting of delays and hidden nodes I usually loop over Ntrials = 10 designs.
You would be surprised how many times only 7 or 8 out of 10 are acceptable.
However, I do initialize the random number generator before the double loop over hidden nodes and random weight initializations.
Hope this helps.
Thank you for formally accepting my answer.
