We present an interior-point method for a family of multifractional pr
ograms with convex constraints. The programs under consideration consi
st of minimizing the maximum of a finite number of linear fractions ov
er some convex set. First, we present a simple short-step algorithm fo
r solving such multifractional programs, and we show that, under suita
ble assumptions, the convergence of the short-step algorithm is weakly
polynomial in a sense specified below. Then, we describe a practical
implementation of the proposed method, and we report results of numeri
cal experiments with this algorithm. These results suggest that the pr
oposed method is a viable alternative to the standard Dinkelbach-type
algorithms for solving multifractional programs.
