想用NSray进行光想优化，设置好了变量和评价函数，但输出框中总是显示“Abnormal Optimization Run Completion - The optimizer cannot modify the variables because of restrictions imposed by active constraints. To allow optimization to continue，consider adjusting or disabling one or more of the constraints.” DtFzT>$^F
但是我并没有设置什么约束条件，请问这个该怎么修改啊？不知道是哪里出了问题
