Add to ORKGTwo algorithms are proposed for computing the maximum degree of a principal minor of specified order of a skew-symmetric rational function matrix. The algorithms are developed in the framework of valuated #DELTA#-matroid of Dress and Wenzel, and are valid also for valuated #DELTA#-matroids in general.
