Problem Size Metrics

Reports scalar-counts and data-dimension metrics for a Problem. Constructed by size_metrics; end users normally call size_metrics(prob) rather than this constructor directly.

Usage

SizeMetrics(
  num_scalar_variables = 0L,
  num_scalar_data = 0L,
  num_scalar_eq_constr = 0L,
  num_scalar_leq_constr = 0L,
  max_data_dimension = 0L,
  max_big_small_squared = 0
)

Arguments

num_scalar_variables

Total scalar entries across all variables in the problem.

num_scalar_data

Total scalar entries across all constants and parameters.

num_scalar_eq_constr

Total scalar entries in equality (Equality, Zero) constraints.

num_scalar_leq_constr

Total scalar entries in inequality (Inequality, NonNeg, NonPos) constraints.

max_data_dimension

Largest single dimension across any data block (constant or parameter).

max_big_small_squared

Maximum of big * small^2 over all data blocks, where big/small are the larger/ smaller dimension of the block.

Value

A SizeMetrics object.
