 You can find the Mathematica notebooks (also in pdf format) of:
 
 - `Klaus`: Main algorithm (logic-based)
-- `Klaus_vs_Theseus`: Comparison between Klaus algorithm and Theseus (see (Phys. Rev. X 11, 031044 (2021))[https://journals.aps.org/prx/abstract/10.1103/PhysRevX.11.031044])
+- `Klaus_vs_Theseus`: Comparison between Klaus algorithm and Theseus (see [Phys. Rev. X 11, 031044 (2021)](https://journals.aps.org/prx/abstract/10.1103/PhysRevX.11.031044))
 - `Monocolored_graphs`: logic clauses to solve the monocromatic edge problem (generation of GHZ states of *n* parties and *d>=n/2* colors)
