Fast sum

titanq.fast_sum(values: Iterable[MathObject]) → Expression

ℹ️ This feature is experimental and may change.

Computes the sum of all elements provided. This function is an faster alternative to the traditional sum() operation for vector-based expressions.

Parameters

values

The VectorExpression or VariableVector whose elements are to be summed.

Returns

Expression

An Expression representing the sum of the elements in exprVector.

Raises

ValueError

If the provided input is not of type VectorExpression or VariableVector.

Examples

>>> from titanq import Model, Vtype
>>> x = model.add_variable_vector('x', 1000, Vtype.BINARY)
>>> y = model.add_variable_vector('y', 1000, Vtype.BINARY)
>>> exprA = fastSum(x + (x * y) - 5 * y)
>>> exprB = fastSum(x)
