Here's my try:
The paper "Gradient Descent is PLS int PPAD-Complete" by Tim Roughgarden, Éva Tardos, and Steven J. Brams presents new results on the limitations of gradient descent algorithm. The authors show that gradient descent has limitations in certain cases, highlighting the importance of considering complexity theory when analyzing algorithms' effectiveness. They also prove that gradient descent is as hard as Either-Solution, making it PLS int PPAD-complete. This result shows that gradient descent is not always effective for all uses and emphasizes the need to understand the nature of computation deeply.
