extends com.google.protobuf.GeneratedMessageV3
implements MPConstraintProtoOrBuilder
     A linear constraint is always of the form:
 lower_bound <= sum of linear term elements <= upper_bound,
 where lower_bound and upper_bound:
 - Can form a singleton: lower_bound == upper_bound. The constraint is an
   equation.
 - Can form a finite interval [lower_bound, upper_bound]. The constraint is
   both lower- and upper-bounded, i.e. "boxed".
 - Can form a semi-infinite interval. lower_bound = -infinity: the constraint
   is upper-bounded. upper_bound = +infinity: the constraint is lower-bounded.
 - Can form the infinite interval: lower_bound = -infinity and
   upper_bound = +infinity. The constraint is free.
