If `n` is even, the string in the `eval` +expression is evaluated as +```ruby + => '[",,,,,"'+ '",' + '",' + '",' + ... + '",' + ' ?=].join#...' + => '[",,,,,"",",",...", ?=].join#...' +``` +where the last double-quote `"` is closing hence the code after `#` is +ignored as comments. Note that `"ab""cd"` in Ruby is equivalent to +`"abcd"`. Therefore the `eval` expression is evaluated into +```ruby + ",,,,,...,=" +``` +where the number of commas is `5+n/2`. +As a result, the regular expression `(.)...\1=` matches `,,,,,=` +at the end of string, that is, at index `5+n/2-5 = n/2`. + +If `n` is odd, the string in the `eval` expression is evaluated as +```ruby + => '[",,,,,"'+ '",' + '",' + '",' + '",' + ... + '",' + ' ?=].join#"].join("3x+1?")' + => '[",,,,,"",",",",...,", ?=].join#"].join("3x+1?")' +``` +where the last element in the array is `", ?=].join#"`.

As a result, the regular +expression `(.)...\1=` matches `?, ?=` at the almost end of string, +that is, at index `5+(n-1)/2*6-1 = 3n+1`, provided that the match +fails in the case of `n = 1` because the symbol `?` occurs only once +in the string. + +One may notice that the string `3x+1` in the code could be other +four-character words.

It receives a data file +from the standard input in the DIMACS CNF that is a standard format +for inputs of SAT solvers. For example, the text in the DIMACS CNF +format, +``` +c +c This is a sample input file. +c +p cnf 3 5 + 1 -2 3 0 +-1 2 0 +-2 -3 0 + 1 2 -3 0 + 1 3 0 +``` +corresponds to a propositional formula in conjunctive normal form, + + (L1 ∨ ¬L2 ∨ L3) ∧ + (¬L1 ∨ L2) ∧ + (¬L2 ∨ ¬L3) ∧ + (L1 ∨ L2 ∨ ¬L3) ∧ + (L1 ∨ L3). + +In the DIMACS CNF format, the lines starting with ``c`` are comments +that are allowed only before the line ``p cnf ...``. The line ``p cnf +3 5`` represents that the problem is given in conjunctive normal form +with 3 variables (L1,L2,and L3) and 5 clauses. A clause is given by a +sequence of the indices of positive literals and the negative indices +of negative literals. Each clause is terminated by ``0``. For the +input above, the program outputs +``` +s SATISFIABLE +v 1 2 -3 +``` +because the formula is satisfiable by L1=true, L2=true, and L3=false. +If an unsatisfiable formula is given, the program should output +``` +s UNSATISFIABLE +``` +This specification is common in most exiting SAT solvers and required +for entries of [SAT competition](http://www.satcompetition.org/). + +The program is very small with no other external libraries thanks to +the wealth of string manipulations in Ruby. It is much smaller than +existing small SAT solvers like [minisat](http://minisat.se/) and +[picosat](http://fmv.jku.at/picosat/)! + + +### Internals + +The basic idea of the program is a translation from DIMACS CNF format +into Ruby. For example, the data file above is translated into a +``Regexp`` matching expression equivalent to +```ruby + '---=-' =~ + /(-?)(-?)(-?)-*=(?=\1$|-\2$|\3$|$)(?=-\1$|\2$|$)(?=-\2$|-\3$|$)(?=\1$|\2$|-\3$|$)(?=\1$|\3$|$)(?=)/ +``` +that returns ``MatchData`` if the formula is satisfiable and otherwise +returns ``nil``. The beginning of regular expression +``(-?)(-?)(-?)-*=`` matches a string ``"---="`` so that each +capturing pattern ``(-?)`` matches either ``"-"`` or `""`, which +corresponds to an assignment of true or false, respectively, for a +propositional variable. Each clause is translated into positive +lookahead assertion like ``(?=\1$|-\2$|\3$|$)`` that matches +``"-"`` only when ``\1`` holds ``"-"``, ``\2`` holds ``""``, or ``\3`` +holds ``"-"``. This exactly corresponds to the condition for +L1∨¬L2∨L3 to be true. The last case ``|$`` never matches +``"-"`` but it is required for making the translation simple. +The last meaningless positive lookahead assertion ``(?=)`` is added +for a similar reason. This translation is based on +[Abigail's idea](http://perl.plover.com/NPC/NPC-3SAT.html) where a +3SAT formula is translated into a similar Perl regular expression. +The differences are the submitted Ruby program translates directly +from the DIMACS CNF format and tries to make the code shorter by using +lookahead assertion which can also make matching more faster. + +Thanks to the ``x`` option for regular expression, the input above is +simply translated into +```ruby + ?-*3+'=-'=~/#{'(-?)'*3}-*=(?= + \1$| -\2$| \3$| $)(?= + -\1$| \2$| $)(?= + -\2$| -\3$| $)(?= + \1$| \2$| -\3$| $)(?= + \1$| \3$| $)(?= + )/x +``` +which has a structure similar to the DIMACS CNF format. + +The part of formatting outputs in the program is obfuscated as an +inevitable result of 'golfing' the original program +```ruby + if ...the matching expression above... then + puts 's SATISFIABLE' + puts 'v '+$~[1..-1].map.with_index{|x,i| + if x == '-' then + i+1 + else + ['-',i+1].join + end + }.join(' ') + else + puts 's UNSATISFIABLE' + end +``` +In the satisfiable case, the MatchData ``$~`` obtained by the regular expression +has the form of +``` + #<MatchData "---=" 1:"-" 2:"-" 3:""> +``` +which should be translated into a string ``1 2 -3``. The golfed code simply +does it by `eval(x+?1)*i-=1` where ``x`` is matched string ``"x"`` or ``""`` +and ``i`` be a negated index. + + +### Data files + +The submission includes some input files in the DIMACS CNF format for +testing the program. + +* [sample.cnf](sample.cnf) : an example shown above. + +* [unsat.cnf](unsat.cnf) : an example of an unsatisfiable formula. + +* [quinn.cnf](quinn.cnf) : an example from Quinn's text, 16 variables and 18 clauses + (available from [http://people.sc.fsu.edu/~jburkardt/data/cnf/cnf.html]) + +* [abnormal.cnf](abnormal.cnf) : an example from [the unofficial manual of the DIMACS challenge](http://www.domagoj-babic.com/uploads/ResearchProjects/Spear/dimacs-cnf.pdf) + where a single clause may be on multiple lines. + +* [uf20-01.cnf](uf20-01.cnf) : an example, with 20 variables and 91 clauses, from [SATLIB benchmark suite](http://www.cs.ubc.ca/~hoos/SATLIB/benchm.html). The last two lines are removed from the original because they are illegal in the DIMACS CNF format (all examples in 'Uniform Random-3-SAT' of the linked page need this modification). + + +### Limitation + +The program may not work when the number of variables exceeds 99 +because ``\nnn`` in regular expression with number ``nnn`` does not +always represent backreference but octal notation of characters. For +example, +```ruby + /#{"(x)"*999}:\502/=~"x"*999+":x" + /#{"(x)"*999}:\661/=~"x"*999+":x" + /#{"(x)"*999}:\775/=~"x"*999+":x" +``` +fail due to the syntax error (invalid escape), while +```ruby + /#{"(x)"*999}:\508/=~"x"*999+":x" + /#{"(x)"*999}:\691/=~"x"*999+":x" + /#{"(x)"*999}:\785/=~"x"*999+":x" +``` +succeed (to return 0) because 508, 691, and 785 are not in octal notation. +Since Ruby 1.9.3 incorrectly returns ``nil`` instead of terminating +with the error for +```ruby + /#{"(x)"*999}:\201/=~"x"*999+":x" + /#{"(x)"*999}:\325/=~"x"*999+":x" +``` +the present SAT solver may unexpectedly return "UNSATISFIABLE" even +for satisfiable inputs. This happens when the number is in octal +notation starting with either 2 or 3. + +In the case of the number starting with 1, the code like the above +does work on all versions of Ruby I tried. For example, +```ruby + /#{"(x)"*999}:\101/=~"x"*999+":x" + /#{"(x)"*999}:\177/=~"x"*999+":x" +``` +succeed (to return 0). Interestingly, +```ruby + /#{"(x)"*999}:\101/=~"x"*999+":\101" + /#{"(x)"*999}:\177/=~"x"*999+":\177" +``` +return ``nil``, while +```ruby + /:\101/=~":\101" + /:\177/=~":\177" +``` +succeed to return 0. The meaning of ``\1nn`` in regular expression +seems to depend on the existence of capturing expressions. + +In spite of these Ruby's behaviors, we have a good news! The present +SAT solver does not suffer from the issues because the program cannot +return solutions in practical time for inputs with variables more than +40. diff --git a/sample/trick2015/ksk_2/sample.cnf b/sample/trick2015/ksk_2/sample.cnf new file mode 100644 index 0000000000..295f81c942 --- /dev/null +++ b/sample/trick2015/ksk_2/sample.cnf @@ -0,0 +1,9 @@ +c +c This is a sample input file. +c +p cnf 3 5 + 1 -2 3 0 +-1 2 0 +-2 -3 0 + 1 2 -3 0 + 1 3 0 diff --git a/sample/trick2015/ksk_2/uf20-01.cnf b/sample/trick2015/ksk_2/uf20-01.cnf new file mode 100644 index 0000000000..0d9503c451 --- /dev/null +++ b/sample/trick2015/ksk_2/uf20-01.cnf @@ -0,0 +1,99 @@ +c This Formular is generated by mcnf +c +c horn?
