Function documentation

void CG_Gen::TruthTable::setSeed(uint_fast32_t i_seed)

setSeed Set the seed for random number generation.

Parameters
i_seed	The seed for random number generation.

This method sets the seed for the random number generator used in generating the truth table. Setting the seed allows for reproducible random number sequences.

Note

Example:

TruthTable table;
table.setSeed(123);

For the getSeed method there is getSeed in RandomGeneratorWithSeed.hpp

void CG_Gen::TruthTable::generateTable(double i_p = 0)

generateTable Generate a truth table with specified probability.

Parameters
i_p	The probability of generating a true value for each cell in the truth table.

This method generates a truth table with the given probability 'i_p". If i_p is greater than 0 and less than or equal to 1.

int32_t CG_Gen::TruthTable::getInput() const

getInput Get the number of input variables in the truth table.

Returns	The number of input variables.

Note

Example:

TruthTable table;
int32_t numInputs = table.getInput();
std::cout << "Number of input variables: " << numInputs << std::endl;

int32_t CG_Gen::TruthTable::getOutput() const

getOutput Get the number of output variables in the truth table

Returns	The number of output variables.

Note

Example:

TruthTable table;
int32_t numOutputs = table.getOutput();
std::cout << "Number of output variables: " << numOutputs << std::endl;

int32_t CG_Gen::TruthTable::size() const

size Get the size of the truth table.

Returns	The size of the truth table (number of rows).

This method returns the total number of rows in the truth table. Each rows corresponds to a unique combination of input values

Note

Example:

// Creating a truth table with 3 input variables and 2 output variables
TruthTable table (3,2);
int32_t tableSize = table.size();
std::cout << "Size of the truth table: " << tableSize << std::endl;

std::vector<std::vector<bool>> CG_Gen::TruthTable::getOutTable() const

getOutTable Get the output table.

Returns	The output table as a two-dimensional vector of boolean values.

This method returns a copy of the entire output table of the truth table. The output table contains the truth values for each combination of input variables.

Note

Example:

// Assuming a truth table with 2 input variables and 1 output variable
TruthTable table(2, 1);
Get the output table
std::vector<std::vector<bool>> outputTable = table.getOutTable();
// Print the output table
std::cout << "Output Table: " << std::endl;
for (const auto& row : outputTable)
{
  for (bool value : row)
  {
    std:: cout << value << " ";
  }
  std::cout << endl;
}

bool CG_Gen::TruthTable::getOutTable(int32_t i, int32_t j) const

getOutTable Get the truth value at a specific position in the output table.

Parameters
i	The row index of the output table.
j
Returns	The truth value at the specified position.

This method returns the truth value at the specified position (i, j) in the output table. The position (i, j) corresponds to the i-th row and j-th column of the output table, representing a specific combination of input variables.

Note

Example:

// Assuming a truth table with 3 input variables and 2 output variable
TruthTable table(3, 2);
// Get the truth value at position (1, 0) in the output table
bool value = table.getOutTable(1,0);

std::vector<std::vector<bool>> CG_Gen::TruthTable::convToBinary() const

convToBinary Convert truth table indices to binary representation This method converts the indices of the truth table into binary representation.

Returns	A two-dimensional vector representing the binary representation of each row index in the truth table.

Each row index of the truth table corresponds to a unique combination of input variables, which is represented in binary form. For example, if the number of input variables is 3, the binary representation of the row index 5 (101 in binary) corresponds to the input combination [true, false, true].

Note

Example:

// Assuming a truth table with 3 input variables and 2 output variable
TruthTable table(3, 2);
Convert truth table indices to binary representation
std::vector<std::vector<bool>> binRepresentation = table.convToBinary();
// Print the binary representation
std::cout << "Binary Representation of Truth Table Indices" << std::endl;
for (cosnt auto& row: binRepresentation)
{
  for (bool bit : row)
  {
    std::cout << bit << " ";
  }
  std::cout << std::endl;
}

void CG_Gen::TruthTable::printTable() const

printTable Print the truth table.

This method prints the entire truth table to the standard output stream. Each row of the truth table is printed as a space-separated sequence of boolean values. After printing the table, a newline character is inserted to separate rows.

Note

Example:

// Assuming a truth table with 3 input variables and 2 output variable
TruthTable table(3, 2);
// Print the truth table
table.printTable();
