• How to Convert a Primal Linear Program to Its Dual
  Convert a linear program to its dual by transposing the constraint matrix, reversing the objective direction, and matching row and variable signs.
• How to Convert a Primal LP Solution to a Dual Solution
  For a linear program, primal variables do not directly become dual variables. Build the dual from the constraints, then use complementary slackness to find its solution.
