    1 # for farmer, this script is necessary to set upper bounds when using piece-wise linear
    2 # approximations of the quadratic penalty term - which can otherwise become unbounded
    3 # for sufficiently large rho values. ultimately, the TOTAL_ACREAGE parameter should be
    4 # correctly taken as the upper bounds in the variable definition, but currently Pyomo
    5 # can only handle constants in this role (and silently ignores parameters).
    6 
    71# only need to set upper bounds on first-stage variables, i.e., those being blended.
