-The versions of the simulation used in the conference proceedings paper ([v1.2](/~https://github.com/symbiotic-engineering/MDOcean/releases/tag/v1.2)) 
-and in the conference video ([v1.3](/~https://github.com/symbiotic-engineering/MDOcean/releases/tag/v1.3)) were later found to have a number of errors. 
-These errors have since been corrected, and the current code ([v1.4](/~https://github.com/symbiotic-engineering/MDOcean/releases/tag/v1.4)) is correct to the best of the authors' knowledge, within the limitations of the stated assumptions. 
-Known areas for improvement are listed as GitHub issues. If you find any additional errors, please let us know.

-Errors that have since been fixed include:
-- Incorrect value for young's modulus of steel
-- Incorrect implementation of force saturation multiplier
-- Wave period and wave height were swapped
-- Froude Krylov force coefficient too high
-- Incorrect nominal controller design variables and objective values
-- Incorrect buckling end condition
-- Nominal simulation did not use power saturation
-- Incorrect scaling of cost with number of WECs
-- Powertrain and transmission loss not accounted for
-- Mass of damping plate support tubes not accounted for
-- Float maximum displacement constraint not being enforced

-*Because the results in the official conference proceedings contain these errors, an updated unofficial version 
-of the paper will be posted here in early September 2022, containing corrections.*
