A proof of the generalized packing-covering conjecture
Abstract
The generalized packing--covering conjecture of Elimelech, Firer and Schwartz asserts that, for every linear code π and every admissible order t, the t-th generalized Hamming weight dt(π) and the t-th generalized covering radius Rt(π) satisfy dt(π)β€ 2Rt(π)+2. We give a computer-assisted proof of the conjecture for every linear code over every finite field and every admissible order. Combining a parity-check reformulation of the conjecture, bounds on the length of putative counterexamples, and successive puncturing arguments, we settle all orders tβ₯ 32 and reduce the remaining orders to finitely many parameter tuples, which we exclude by an exact computer verification.
