运算过程中提示操作符不当有待改善01
程序段如下：
   !***********************************************************************
Subroutine hbfds(n, w, c, m, kk, k, x, jdim)

!c*********************************************************************72
!c
!cc HBFDS performs a best-fit decreasing heuristic.
!c
!c for local use with current solution given.
!c time complexity  o(n**2) .
!c
  Integer w(jdim), c, k(jdim), x(jdim), kk(jdim)
  Do j = 1, m
    k(j) = kk(j)
  End Do

  Do i = 1, n
!c
!c insert the next item.
!c
    iwi = w(i)
    minres = c
    Do j = 1, m
      kres = k(j) - iwi
      If (kres<0) Goto 20
      If (kres>=minres) Goto 20
      minres = kres
      jm = j
    20 End Do
3366|    If (minres . lt . c) Goto 30
!c
!c initialize a new bin.
!c
    m = m + 1
    k(m) = c - iwi
    x(i) = m
    Goto 40
!c
!c insert the item  into an old bin.
!c
    30 k(jm) = k(jm) - iwi
    x(i) = jm
  40 End Do

  Return
End Subroutine hbfds
