论文中曲率求导的公式1. delta_G/delta_dsigma = 2*(ddsigma^T * B * dsigma) / ||dsigma||_2^3 *(.....) 2. delta_G/delta_ddsigma = 2(ddsigma^T* B* dsigma)(...), 在代码实现中公式1，只计算了括号内的，没有计算括号前的内容， 公式2， 括号内disigma二范数的6次方， 代码为 3次方，括号前的内容也没有计算，请问，代码是否计算错误，还是有意省略

undefined reference to `bool absl::lts_20230802::str_format_internal::FormatA rgImpl::Dispatch

Hi, we can obtain the simulation process of unstructured environments from the doc, but how can we simulate dynamic urban road environments? Could you provide some guidance on this?
