I have compared Deepseek and ChatGPT, and it seems that Deepseek excels in solving math problems. I provided the same prompt to both tools to evaluate their performance:
“A man is standing on one side of a river, with two parallel banks 10 meters apart. He needs to swim across the river and then run 20 meters along the opposite bank. He swims at a speed of 1 meter per second and runs at a speed of 6 meters per second. Rather than swimming directly perpendicular to the riverbank, which path should he take to minimize his total travel time?”
