linopy.piecewise.PiecewiseFormulation

class linopy.piecewise.PiecewiseFormulation(name, method, variable_names, constraint_names, model, convexity=None)

Result of add_piecewise_formulation.

Groups all auxiliary variables and constraints created by a single piecewise formulation. Stores only names internally; variables and constraints properties return live views from the model.

name

Formulation name (used as prefix for auxiliary variables and constraints).

Type:

str

method

Resolved method actually used. Never "auto"; if the caller passed method="auto", this holds the method that was chosen.

Type:

PWL_METHOD

convexity

Shape of the piecewise curve along the breakpoint axis when it is well-defined (exactly two expressions, non-disjunctive, strictly monotonic x breakpoints). None otherwise.

Type:

PWL_CONVEXITY or None
