Mon, 29 Oct 2007 12:54:19 +0100 + + exposed guts of gfsm_automaton_compose() + - compose_prepare() into compose_old_prepare_fsm1(), compose_old_prepare_fsm2() + - should make it easier to hack a cascade implementation + +v0.0.8 Thu, 15 Feb 2007 12:05:41 +0100 + + updated build system to build more cleanly on non-development systems + - e.g. missing optgen.perl, flex, bison, pod2x, perl, etc. + + added gfsm.magic snippet for /etc/magic + - added 'install-magic' and 'uninstall-magic' targets for + manual magic maintainance, since there seems to be no good and safe + way to do this automagically (ugh)... + + added support for final weights + + changed binary format (backwards-compatible with dispatch function) + + added final-weight operations final_weight_(plus|times)() + + added optional(), replace(), insert_automaton() + + added lookup_viterbi(), viterbi_trellis_paths(), viterbi_trellis_bestpath() + + fixed a bug in gfsm_automaton_renumber_states() + + fixed a really stupid bug in gfsm_arclist_insert_link() for sorted insertion + + fixed some bugs in gfsm_automaton_rmepsilon() + + fixed an epsilon-related bug in compose() and intersect() + + fixed another epsilon-related bug in compose() + - implemented algorithm from: + Mohri, Pereira, & Riley (1996), "Weighted Automata in Text and Speech + Processing", Proc. ECAI '96, John Wiley & Sons, Ltd. + - calling conventions changed for compose_full() + + added gfsmScanner.[ch], gfsmRegexCompiler.[ch] + + added gfsmTrie, (quasi-)deterministic input acceptor (i/o pairs) + - currently geared towards storing frequencies + + added gfsmIO.[ch] : abstract I/O layer + - includes basic zlib compression support + - currently used only for text & binary automaton I/O, also text alphabet I/O + - TODO: use I/O layer for alphabet draw methods? regex compiler? + + added gnulib code for vasprintf(), getdelim() + - removed old gfsmCompat.h hack + +v0.0.7 Sun, 20 Nov 2005 14:39:33 +0100 + + added lookup(), paths(), path<->string conversion functions + + added semiring type "plog" (positive logs), added stable gfsm_log_add() function + + added intersect(), compose(), difference(), product(), rmepsilon() operations + + gobble less memory on load_bin_file() -- load states & arcs incrementally + - doing this right would require a stored binary file incompatibility, currently hacked. + + fixed a number of small bugs + +v0.0.6 Mon, 12 Sep 2005 01:45:46 +0200 + + added mingw32 patch (getline) + +v0.0.5 Wed, 22 Sep 2004 00:23:49 +0200 + + removed references to file "LICENSE" in header comments + + fixed small size bug in clear() for gfsmUserAlphabet + + added key-stringification to gfsm_automaton_draw() methods + +v0.0.4 Tue, 14 Sep 2004 15:57:56 +0200 + + fixed bug in gfsm_alphabet_size() for user alphabets + +v0.0.3 Mon, 13 Sep 2004 10:25:23 +0200 + + added some algebraic operations, fixed some bugs + +v0.0.2 Thu, 2 Sep 2004 17:34:18 +0200 + + basic accessors and algebra + +v0.0.1 Tue, 24 Aug 2004 11:34:59 +0200 + + created |
