Struct Problem 

Source
pub struct Problem<N, F: Flag> {
    pub ineqs: Vec<Ineq<N, F>>,
    pub cs: Vec<MulAndUnlabel<F>>,
    pub obj: QFlag<N, F>,
}
Expand description

The optimization problems over flags are translated into a sdp problem in the sdpa format.

Shape of the matrices:

For each i in ineqs (where i is itself a vector of inequalities): A diagonal block of size i.len()

For each cs: A block with the size od cs.input_matrix An optimization problem expressed in flags algebra.

Fields§

§ineqs: Vec<Ineq<N, F>>

Set of contraint inequalities.

§cs: Vec<MulAndUnlabel<F>>

Set of Cauchy-Schwarz inequalities to be used.

§obj: QFlag<N, F>

Vector to be optimized.

Implementations§

Source§

impl<N, F: Flag> Problem<N, F>

Source

pub fn minimize(obj: QFlag<N, F>) -> Self
where N: Display + Num + FromPrimitive + Clone + Neg<Output = N>,

Create a minimization problem with the argument as objective function.

Source

pub fn check(&self)

Panic if the size of the basis involved are inconsistent.

Source§

impl<N, F> Problem<N, F>
where N: Display + Zero + Copy + PartialEq + Neg<Output = N>, F: Flag,

Source

pub fn write_sdpa(&self, filename: &str) -> Result<()>

Write the semi-definite program in the file filename in the sdpa format.

Source

pub fn no_scale(self) -> Self

Rescale the objective according to its scale field. If this method is not used, the output of the sdp solver may need to be rescaled.

Source

pub fn solve_csdp(&self, filename: &str) -> Result<f64, Error>

Solve the sdp using the CSDP solver.

Source

pub fn run_csdp( &self, name: &str, initial_solution: Option<&str>, minimize_certificate: bool, ) -> Result<f64, Error>
