Hi,
This model will have a serious sign problem and I thus do not expect any successful simulations

Dear Alps users
I am trying to do a QMC simulation of the J1-J2-model on the s=1 rectangular lattice using the "dirloop_sse" app. I am fairly new to using Alps, so I was wondering if someone would verify that my input parameters are correct. My parameter files contains:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="ALPS.xsl"?>
