get_problem_data function

Get Problem Data

Get the problem data used in the call to the solver.

get_problem_data(object, solver, gp)

Arguments

• object: A Problem object.
• solver: A string indicating the solver that the problem data is for. Call installed_solvers() to see all available.
• gp: (Optional) A logical value indicating whether the problem is a geometric program.

Returns

A list containing the data for the solver, the solving chain for the problem, and the inverse data needed to invert the solution.

Examples

a <- Variable(name = "a")
data <- get_problem_data(Problem(Minimize(exp(a) + 2)), "SCS")[[1]]
data[["dims"]]
data[["c"]]
data[["A"]]

x <- Variable(2, name = "x")
data <- get_problem_data(Problem(Minimize(p_norm(x) + 3)), "ECOS")[[1]]
data[["dims"]]
data[["c"]]
data[["A"]]
data[["G"]]
