00041  * Revision 1.1  2006/04/05  20:27:30  dhdfu
00042  * A Great Reorganzation of header files and executables
00043  * 
00044  * Revision 1.2  2006/02/23 05:16:14  arthchan2003
00045  * Merged from branch SPHINX3_5_2_RCI_IRII_BRANCH: Add wrapper of flat_fwd.c
00046  *
00047  * Revision 1.1.2.5  2006/01/16 20:11:23  arthchan2003
00048  * Interfaces for 2nd stage search, now commented.
00049  *
00050  * Revision 1.1.2.4  2005/11/17 06:42:15  arthchan2003
00051  * Added back crossword triphone traversing timing for search. Also. for consistency with srch.c.  Some dummy code of IBM lattice conversion was added. They are now bypassed because it is not fully function.
00052  *
00053  * Revision 1.1.2.3  2005/09/25 19:23:55  arthchan2003
00054  * 1, Added arguments for turning on/off LTS rules. 2, Added arguments for turning on/off composite triphones. 3, Moved dict2pid deallocation back to dict2pid. 4, Tidying up the clean up code.
00055  *
00056  * Revision 1.1.2.2  2005/09/18 01:45:19  arthchan2003
00057  * Filled in all implementation in srch_flat_fwd.[ch], like the FSG mode, it takes care of reporting itselft.
00058  *
00059  * Revision 1.1.2.1  2005/07/24 01:40:37  arthchan2003
00060  * (Incomplete) The implementation of flat-lexicon decoding.

00068  * SOME ASSUMPTIONS
00069  *   - All phones (ciphones and triphones) have same HMM topology with n_state states.
00070  *   - Initial state = state 0; final state = state n_state-1.
00071  *   - Final state is a non-emitting state with no arcs out of it.
00072  *   - Some form of Bakis topology (ie, no cycles, except for self-transitions).
00073  *
