Methods

__init__()
collect_op()	interface function Performing common sub-expression elimination Should be called after contract_simplify_compile(*exprs) or mk_cexpr(*exprs) The cexpr cannot be evaluated before collect_op!!! eval term factor
copy()	return a deep copy of this object.
get_expr_names()
list()
optimize()	interface function
