Poster Title:  Optimization of tensor transportation in higher-order tensor renormalization group
Poster Abstract: 

Higher-order tensor renormalization group (HOTRG) is one of approximation methods for the partition function in physics. Bottleneck computation of HOTRG is a tensor contraction which is a generalization of matrix product. A tensor contraction is usually implemented by matrix products and tensor transportations which is a generalization of matrix transportation. Tensor transportations in HOTRG take a lot of time because it is complicated and applied to large tensors. In this research, we reduce computation time for the tensor transportations in HOTRG by optimizing tensor transportation procedure.
