Hi, Alois,

Renumbering is not limited to produce constant bandwidth. As stated in my
origianl response, if the upper triangular part
is as:

/ \
| x x |
| x x |
| x x |
| x x |
| x x |
| x x |
| x |
\ /

variable bandwidth solver (i.e., skyline solver) is a choice.
Hello,
this case and the transposed one are quite trivial, but if there is a
full row and full column, then renumbering doesn't help much and you
need a different method.
