Arie Gurfinkel b50da20531 array_mbp: turn on model completion 2018-06-14 16:08:50 -07:00
Arie Gurfinkel 0452bc3d43 qe_lite: simplify definitions before deciding on elimination order 2018-06-14 16:08:50 -07:00
Arie Gurfinkel b120923dd5 qe_lite: bug fix in der::der_sort_vars() 
The case of

VAR 1 = (+ (:var 2) 10)
VAR 2 = (+ 0 foo)

was not properly handled whenever VAR2 has only one reference.
In that case, VAR2 is not marked as done when VAR1 is processed,
causing VAR2 to be duplicated in elimination order

Arie Gurfinkel d06f4bd337 Fix reset of params_ref in solver 
params_ref is not a ref, and params_ref::reset is not ref::reset.

params_ref::reset resets the params object being pointed to by
params_ref.

A proper way to reset a params_ref as a reference is to assign an
empty params_ref object to it.
