The average errors are the 0.03%-5.0% for the binaries and the 4.11%-25.2% for the ternary which is less than that (4.84%-41.2%) of the sub-regular solution model (SRSM). This shows that MIVM is more effective and reliable than SRSM for the ternary and does not depend on a polynomial approximation with some ternary adjustable parameters.展开更多
