SVD using the divide and conquer algorithm might fail for certain tensors.

Currently the default algorithm for singular value decomposition is a divide and conquer algorithm. From an optimization perspective this is great. Indeed, for large tensors such algorithms outperform the standard...

Plotting error measures during groundstate searches

3

When performing groundstate searches requiring many iterations it is desirable to have some notion of convergence speed to estimate runtime on clusters and better help planning. I used to have...

Whilst trying out the imaginary time evolution MPO I found out that the @show function for sparse_MPO doesn't work. A MWE is : ```julia using MPSKitModels Ham = MPSKitModels.transverse_field_ising(); expham...

Undefined constructor.

Hi, I'm using the AD extension of TensorKit and ran into some problems due to this line : https://github.com/Jutho/TensorKit.jl/blob/419f88cb25bdbd3698606990f9f4cd131156f0c4/ext/TensorKitChainRulesCoreExt/constructors.jl#L25 From what I understand the ``tol kwarg`` has been removed from...

This PR makes Gradient Descent parallelized using Threads.@spawn

As the title suggest this PR makes Gradient descent parallel... Two remarks are : 1) I failed to parallelize : ```julia function retract(x::ManifoldPoint{

Parallel vumpssvd

This PR also makes vumpSVD parallel. Again tests have been implemented in another PR and I've tested the combined PR locally on my machine :)
