Three types of experiments were carried out: short-term, middle-term, and long-term test. In each test, randomly selected 100 samples as training samples and others as testing samples. The ME, MSE of profit forecast and ∆V are shown in Tables 2–4, respectively, where AV1 and UB1 represent average value (AV) and upper bound (UB) of ME and MSE in short-term test, AV2 and UB2 indicate that in medium-term test, and AV3 and UB3 mean that value of long-term test. Fig 7 shows the radar chart of average value of ME and MSE in different terms for various bi-objective algorithms.
