Industrial knitting machines form fabric by manipulating loops of yarn held on hundreds of hook-shaped needles. Transfer planning algorithms generate a sequence of machine instructions that move loops between their current needles and given target needles. In this paper we describe how to compute the run-time cost of a transfer plan in terms of machine passes, and compare the plans generated by several existing and new transfer planning algorithms under this metric over a a large benchmarking set of transfer operations taken from example flat lace patterns, along with synthetically generated patterns.
