  <STRONG>Description:</STRONG> 
  <UL></UL>
  <LI>This program requires an integer-coded training image, a series of initial 
  integer-coded realizations (possibly only one) to post-process, and 
  information about what components of a two-point histogram are to be 
  reproduced. The integer coding could be derived naturally from a categorical 
  variable or it could be derived from the discretization of a continuous 
  variable.

  <STRONG>Parameters:</STRONG> 
  <UL>
    <LI><B>datafl:</B> a file that contains the input realizations to 
    post-process. The realizations must be integer-coded. The maximum number of 
    different integer codes is specified in <TT>anneal.inc</TT>. The input file 
    has one integer per line cycling fastest on <I>x</I>, then <I>y</I>, then 
    <I>z</I>, then by realization. 
    <LI><B>trainfl:</B> a file with the training image. The training image 
    <I>must</I> have the same integer code values as the realizations to 
    post-process and have the same size and discretization. 
    <LI><B>idbg</B> and <B>report:</B> an integer debugging level between 0 and 
    3, and a reporting interval. After a fixed number of iterations 
    (<B>report</B>) the realization is written to the output file. 
    <LI><B>dbgfl:</B> file for the debugging information. 
    <LI><B>outfl:</B> the output file that will contain the post-processed 
    realizations. 
    <LI><B>nsim:</B> the number of initial realizations to post process. 
    <LI><B>nx, ny,</B> and <B>nz:</B> definition of the grid system. 
    <LI><B>seed:</B> random number seed (a large odd integer). 
    <LI><B>maxit</B> and <B>tol:</B> the maximum number of iterations over the 
    entire grid network. Typically 99\% of the improvement is reached in 5 
    iterations and the remaining 1\% may be reached by 10 iterations. More than 
    10 iterations is not recommended. The initial objective function is 
    normalized to one; when it is lowered to <B>tol</B> the simulation is 
    stopped. 
    <LI><B>ndir:</B> the number of directions for the two-point histogram 
    control. For each direction the following parameters are needed: 
    <UL>
      <LI><I>ixl:</I> the offset in the <I>x</I> direction for a unit lag 
      <LI><I>iyl:</I> the offset in the <I>y</I> direction for a unit lag 
      <LI><I>izl:</I> the offset in the <I>z</I> direction for a unit lag 
      <LI><I>nlag:</I> the number of lags </LI></UL></LI></UL></DT></DL><IMG height=8
