We study the online strip packing problem and derive an improved lower bound ofρ≥2.589… for the competitive ratio of this problem. The construction is based on modified “Brown-Baker-Katseff sequences” (Brown et al. in Acta Inform. 18:207–225, 1982) using only two types of rectangles. In addition, we present an online algorithm with competitive ratiofor packing instances of this type.
