Duan and Mehlhorn and Duan, Garg, and Mehlhorn presented polynomial time combinatorial algorithms [DM13, DGM15] for the computation of equilibrium prices in linear exchange markets. I am currently implementing these algorithms. I discuss the questions that I hope to answer through the implementation.

Clearly
\(b_1 \ge |r(B)|/n\). Also,
\({r(b_j)}/{r(b_{j+1})}\le 1+1/n\) for
\(j<\ell \), and hence
\(r(b_\ell )\ge r(b_1)/(1+1/n)^{-n} \ge r(b_1)/e \ge |r(B)|/(e \cdot n)\).
