/* Given a basic map with at least two parallel constraints (as found
18
 * by the function parallel_constraints), first look for more constraints
19
 * parallel to the two constraint and replace the found list of parallel
20
 * constraints by a single constraint with as "input" part the minimum
21
 * of the input parts of the list of constraints.  Then, recursively call
22
 * basic_map_partial_lexopt (possibly finding more parallel constraints)
23
 * and plug in the definition of the minimum in the result.
24
 *
25
 * As in parallel_constraints, only inequality constraints that only
26
 * involve input variables that do not occur in any other inequality
27
 * constraints are considered.
28
 *
29
 * More specifically, given a set of constraints
30
 *
31
 *  a x + b_i(p) >= 0
32
 *
33
 * Replace this set by a single constraint
34
 *
35
 *  a x + u >= 0
36
 *
37
 * with u a new parameter with constraints
38
 *
39
 *  u <= b_i(p)
40
 *
41
 * Any solution to the new system is also a solution for the original system
42
 * since
43
 *
44
 *  a x >= -u >= -b_i(p)
45
 *
46
 * Moreover, m = min_i(b_i(p)) satisfies the constraints on u and can
47
 * therefore be plugged into the solution.

/* Compute the lexicographic minimum (or maximum if "flags" includes
171
 * ISL_OPT_MAX) of "bmap" over the domain "dom" and return the result as
172
 * either a map or a piecewise multi-affine expression depending on TYPE.
173
 * If "empty" is not NULL, then *empty is assigned a set that
174
 * contains those parts of the domain where there is no solution.
175
 * If "flags" includes ISL_OPT_FULL, then "dom" is NULL and the optimum
176
 * should be computed over the domain of "bmap".  "empty" is also NULL
177
 * in this case.
178
 * If "bmap" is marked as rational (ISL_BASIC_MAP_RATIONAL),
179
 * then we compute the rational optimum.  Otherwise, we compute
180
 * the integral optimum.
181
 *
182
 * We perform some preprocessing.  As the PILP solver does not
183
 * handle implicit equalities very well, we first make sure all
184
 * the equalities are explicitly available.
185
 *
186
 * We also add context constraints to the basic map and remove
187
 * redundant constraints.  This is only needed because of the
188
 * way we handle simple symmetries.  In particular, we currently look
189
 * for symmetries on the constraints, before we set up the main tableau.
190
 * It is then no good to look for symmetries on possibly redundant constraints.
191
 * If the domain was extracted from the basic map, then there is
192
 * no need to add back those constraints again.
