Hi ns-developers, I've probably found a bug in srm-adaptive.tcl, line 275 of the ns-2.1b2 = release. In method "SRM/repair/Adaptive instproc closest-repairor?", the line [expr 1.5 * [$self distance? requestor_]]} { is wrong and must be [expr 1.5 * [$self distance? $requestor_]]} { Maybe you can fix the problem in future releases. Regards, -Chris.
