      I enabled trace logging above, it happens in the 3th move of the first step.

      It seems like this rule is responsible:

      // 1 democrat and 1 republican = 2 politians at each table but NOT two of the same kind
      // 2 doctors at each table but NOT two of the same kind
      // 2 coaches at each table but NOT two of the same kind
      // 2 programmers at each table but NOT two of the same kind
      // 2 socialites at each table
      // 2 teachers at each table
      rule "twoSameJobTypePerTable"
          when
              $jobType : JobType()
              $table : Table()
              not (
                  SeatDesignation(guestJobType == $jobType, seatTable == $table, $leftId : id, $firstJob : guestJob)
                  and SeatDesignation(guestJobType == $jobType, seatTable == $table, id > $leftId,
                          differentKindIfNeeded($firstJob))
              )
          then
              scoreHolder.addConstraintMatch(kcontext, -100);
      end
