Cone tag constants

Source: R/diffcp-package.R
diffcp-cones.Rd

String keys matching the SCS / Clarabel cone conventions. Used as names in the cone_dict argument to solve_only() and solve_and_derivative(), and in the (name, size) pairs returned by parse_cone_dict().

Usage

ZERO

EQ_DIM

POS

SOC

PSD

EXP

EXP_DUAL

CONES

Format

Character scalars (and one character vector, CONES).

Details

  • ZERO ("z"): zero cone (equality constraints).

  • EQ_DIM: alias of ZERO.

  • POS ("l"): nonnegative orthant.

  • SOC ("q"): second-order cone.

  • PSD ("s"): symmetric positive semidefinite cone.

  • EXP ("ep"): primal exponential cone.

  • EXP_DUAL ("ed"): dual exponential cone.

  • CONES: the canonical SCS ordering of cone tags.
