Sim_DllAddLit()
Add a literal `lit' to the current clause. `lit' must be an integer such that its absolute value is greater than 0 and smaller than or equal to the biggest allowed variable index. A positive (negative) integer denotes a positive (negative) occurrence of the corresponding variable. If `lit' does not fulfill the above conditions, or if there is no pending clause to add `lit' to, -1 is returned. The function returns 0 if the pending clause becomes tautologous, and 1 otherwise. Redundant literals are always discarded.
Sim_DllClear()
Destroys the internal data structure.
Sim_DllCommitCl()
Commit the pending clause. If there is no such clause, or the given `clId' is differente from the current one, -1 is returned. If the committed clause is empty, 0 is returned and the function resets the state (no pending clause). On success, `clId' is returned.
Sim_DllGetSolution()
Get the current assignment to propositions. The returned object is an array of integers indexed on propositions. For each proposition, the values SIM_TT, SIM_FF, SIM_DC are given, meaning that the proposition was assigned to true, false or not assigned at all (Don't Care). Propositions that did not occur in the formula receive a default value of SIM_DC.
Sim_DllGetStack()
Get the current search stack contents. The returned object is an array of all the propositions that received a truth value, encoded as literals (negative value if the proposition was assigned to false and vice versa).
Sim_DllInit()
Initialize the DLL module. The array `params' must contain the following elements:
Idx Default value Parameter Notes -------------------------------------------------------------- 0 1200 SIM_TIMEOUT seconds 1 10 << 20 SIM_MEMOUT megabytes 2 SIM_BOEHM_HEUR SIM_HEURISTIC 0..SIM_HEUR_NUM 3 1 SIM_SOL_NUM N >= 1 4 3 SIM_LEARN_ORDER N >= 2 5 SIM_RELEVANCE SIM_LEARN_TYPE SIM_RELEVANCE/SIM_SIZE 6 0 SIM_MODEL_PROPS 0/1 7 SIM_NONE SIM_PPROC_STRENGTH 0..SIM_RESOLVE 8 0 SIM_RND_SEED N >= 0 9 0 SIM_VERBOSITY 0/1 10 0 SIM_HEUR_PARAM N >= 0 11 100 SIM_MAX_VAR_NUM N > 1 12 1000 SIM_MAX_CL_NUM N > 1 -------------------------------------------------------------- The default inizialization can be requested by setting the corresponding element to SIM_ASK_DEFAULT. Notice that the actual number of variables and clauses in the formula *cannot* be greater than SIM_MAX_VAR_NUM and SIM_MAX_CL_NUM respectively. Failing to dimension these parameters correctly will cause the solver to crash.
Sim_DllNewClSize()
Create a new (empty) clause and return its unique id, (an integer code greater than or equal to 0). The clause is dimensioned to accomodate `size' literals without reallocations. Trying to add a new clause without committing any pending one yields -1 as a return value.
Sim_DllNewCl()
Create a new (empty) clause and return its unique id (an integer code greater than or equal to 0). Trying to add a new clause without committing any pending one yields -1 as a return value.
Sim_DllParseDimacs()
Parses a DIMACS cnf problem file into a DLL module.
Sim_DllPrintFormulaDimacs()
Print the formula in the DLL module using DIMACS format.
Sim_DllPrintModel()
Print the model.
Sim_DllPrintParams()
Prints parameters (configuration).
Sim_DllPrintResult()
Prints the result (formatted).
Sim_DllPrintStats()
Prints internal statistics.
Sim_DllPrintTimers()
Prints internal timers.
Sim_DllPropIsModel()
State model membership, i.e., a proposition that is not dependent or defined. 'prop` must be a positive non-zero integer smaller than or equal to the biggest allowed variable index.
Sim_DllSolve()
Solves a formula using the Davis-Logemann-Loveland algorithm.
