Removed remove_short_loops functionality.
[libdai.git] / ChangeLog
1 libDAI-0.2.2 (2008-??-??)
2 -------------------------
3
4 * Now compiles also under Visual C++.
5 * Added Exceptions framework.
6 * Replaced ENUM2,ENUM3,ENUM4,ENUM5,ENUM6 by single DAI_ENUM macro.
7 * Removed utils/remove_short_loops and matlab/remove_short_loops.
8 * Added more features to utils/createfg for creating factor graphs.
9 * Pervasive change of BipartiteGraph implementation (based on an idea by
10 Giuseppe Passino). BipartiteGraph no longer stores the node properties
11 (former _V1 and _V2), nor does it store a dense adjacency matrix anymore,
12 nor an edge list. Instead, it stores the graph structure as lists of
13 neighboring nodes. This yields a significant memory/speed improvement for
14 large factor graphs, and is more elegant as well. Iterating over neighbors is
15 made easy by using boost::foreach.
16 * Improved index.h (merged from SVN head):
17 - Renamed Index -> IndexFor
18 - Added some .reserve()'s to IndexFor methods which yields a
19 25% speedup of testregression
20 - Replaced multind by Permute
21 - Added MultiFor
22 - Added State
23 * Moved everything into namespace "dai"
24 * Renamed DEBUG to DAI_DEBUG to avoid conflicts
25 * Added conditional compilation of inference methods
26 * Contributions by Peter Gober:
27 - Renamed variable _N in mr.* for compatibility with g++ under cygwin
28 * Contributions by Giuseppe Passino:
29 - removed "using namespace std;" from header files - bad practice
30 - moved header files in include/dai and sources in src
31 - changed #ifndefs to GNU style
32 - added extra warning checks (-W -Wextra) and fixed resulting warnings
33 - dai::TProb:
34 o removed copy constructor and assignment operators (redundant)
35 o implementation of some methods via STL algorithms
36 o added methods takeExp, takeLog, takeLog0 for transformation in-place
37 o explicit constructor (prevents implicit conversion from size_t to TProb)
38 o added operator+,+=,-,-=, with argument T (for calculations in log-scale)
39 - Added "logdomain" property to BP, a boolean that controls whether
40 calculations are done in the log-domain or in the linear domain;
41 doing calculations in the log-domain may help if the numerical range
42 of a double is too small.
43 * Contributions by Christian Wojek:
44 - New FactorGraph constructor that constructs from given ranges of factors
45 and variables
46 - Optimization of FactorGraph constructors using tr1::unordered_map.
47 * FactorGraph constructors no longer check for short loops (huge speed
48 increase for large factor graphs), nor for negative entries. Also, the
49 normtype is now Prob::NORMPROB by default.
50 * VarSet is now implemented using a std::vector<Var> instead of a
51 std::set<Var>, which yields a significant speed improvement.
52 * Improved MaxSpanningTreePrims algorithm (uses boost::graph)
53 * Small optimization in Diffs
54 * Replaced Complex with real numbers (negative potentials is just not
55 used enough to warrant the additional "complexity" :))
56 * Moved Properties and MaxDiff frameworks from InfAlg to each individual
57 inference algorithm, because the Properties framework was not as
58 convenient as I hoped, and not every inference algorithm needs a maxdiff
59 variable. Also, replaced some FactorGraph functionality in InfAlg by a
60 function that returns the FactorGraph. The result is cleaner (less
61 entangled) code.
62 * Improved ClusterGraph implementation, yielding significant speedups
63 for the JunctionTree algorithm on large factorgraphs.
64 * Improved documetation
65 * Interface changes:
66 - VarSet::
67 stateSpace() -> states()
68 VarSet( const std::set<Var> ) -> VarSet( begin, end, sizeHint=0 )
69 VarSet( const std::vector<Var> ) -> VarSet( begin, end, sizeHint=0 )
70 removed bool operator||
71 operator&&(const VarSet&) -> intersects(const VarSet&)
72 operator&&(const Var&) -> contains(const Var&)
73 - FactorGraph::
74 delta(const Var &) -> delta(size_t)
75 Delta(const Var &) -> Delta(size_t)
76 makeCavity(const Var &) -> makeCavity(size_t)
77 vars() -> vars
78 factors() -> factors
79 removed MakeFactorCavity(size_t)
80 removed ExactMarginal(const VarSet &)
81 removed ExactlogZ()
82 moved isConnected() to BipartiteGraph
83 removed updatedFactor(size_t)
84 removed _normtype and NormType()
85 - RegionGraph::
86 nr_ORs() -> nrORs()
87 nr_IRs() -> nrIRs()
88 ORs() -> ORs
89 IRs() -> IRs
90 - *::Regenerate() -> *::create()
91 - Renamed Index -> IndexFor
92 - Diffs:
93 max() -> maxDiff()
94 max_size() -> maxSize()
95 - Prob::max() -> Prob::maxVal()
96 - Factor::max() -> Factor::maxVal()
97 - toc() in util.h now returns seconds as a double
98 - VarSet::operator&&
99 - Properties -> PropertySet
