摘要  The simple continued fraction expansion of a single real number gives the best solution to its rational approximation problem. A multidimensional generalization of the simple continued fraction expanding procedure is the Jacobi-Perron algorithm (JPA). This algorithm and its modifications are borrowed to study the multi-rational approximation problem over the formal Laurent series field F((z~(-1))), which is related to the multi-sequence synthesis problem in the field of communication and cryptography, but none of these algorithms guanrantee the best
