Hi, I'm having problems to recall the name of doing something with quadratic complexity when it can be solved linearly.
For example, using a get-by-index function to iterate over a linked list instead of just using a next-element is the typical case of this antipattern.
I think it was the "something painter", as a metaphor of a guy that is painting a road, but doesn't carry with him the paint bucket and has to come back to the starting point every time he needs to refill the brush.
Cheers.
You're probably thinking of Schlemeil the Painter's Algorithm.
There's a classic joke on the topic that Joel Spolsky included in one of his blog articles some years ago:
Shlemiel gets a job as a street painter, painting the dotted lines down the middle of the road. On the first day he takes a can of paint out to the road and finishes 300 yards of the road. "That's pretty good!" says his boss, "you're a fast worker!" and pays him a kopeck.
The next day Shlemiel only gets 150 yards done. "Well, that's not nearly as good as yesterday, but you're still a fast worker. 150 yards is respectable," and pays him a kopeck.
The next day Shlemiel paints 30 yards of the road. "Only 30!" shouts his boss. "That's unacceptable! On the first day you did ten times that much work! What's going on?"
"I can't help it," says Shlemiel. "Every day I get farther and farther away from the paint can!"
P.S. Don't confuse this with the Painter's Algorithm, which is an actual method for composing images.
