Hi,I'm writing a procedure where I make some modifications to the basis of a simplex tableau by pivoting pairs of variables (using the lpx_set_[col|row]_stat and lpx_warm_up functions). I then check the status of the basic solution I obtain using lpx_get_status. One of the status that can be reported by GLPK is: LPX_UNDEF, "solution is undefined". Does anyone know what this means for GLPK, please ?
Thanks in advance, -- Olivier Liess
