Method->NMinimize in FindFit Crashes the Kernel

*To*: mathgroup at smc.vnet.net*Subject*: [mg89539] Method->NMinimize in FindFit Crashes the Kernel*From*: Kezhao Zhang <kezhao.zhang at gmail.com>*Date*: Thu, 12 Jun 2008 02:58:50 -0400 (EDT)

I am running Mathematica 6.0.2.1 on 32-bit Windows Vista with 3GB of RAM. The following code crashes the Kernel: x = Range[1, 10, 0.01]; y = Exp[-0.1 x]; FindFit[Thread[{x, y}], 1 - 1/2 Erfc[(m - Log[t])/(Sqrt[2] s)], {s, m}, t, Method -> NMinimize] FindFit with Method->NMinize works fine when the number of data points is small, e.g., x=Range[1,10,0.1]. I wonder whether this is a bug or there is a way to prevent the kernel crash. Thanks. Kezhao
