These challenges exist to make it harder for hackers to access your accounts. The characters can't be read by a computer and must be entered manually, ensuring only a real person can pass the test. Why am I being ...

The following year, Google began to deploy a new reCAPTCHA API, featuring the "no CAPTCHA reCAPTCHA"—where users deemed to be of low risk only need to click a single checkbox to verify their identity. A ...
NOTE: reCAPTCHA.net has officially been solved algorithmically. Here is the slashdot article It was also presented at DEFCON 18, the largest hacking convention in the world. —Preceding unsigned comment added by 98.250.57.53 04:24, 6 August 2010 (UTC) Why some editors are removing the reCaptcha solver part ?
Web scraping is the process of automatically mining data or collecting information from the World Wide Web. It is a field with active developments sharing a common goal with the semantic web vision, an ambitious initiative that still requires breakthroughs in text processing, semantic understanding, artificial intelligence and human-computer interactions.
In order for the CAPTCHA to be resistant to such chance-guessing botnet attacks, the user would need to be forced to solve an annoyingly large number of images. recaptcha uses words from the English language, which only has about +/- 50,000 words. I'm not sure this is even a weakness, and it seems to be the Wikipedia article's opinion.
Robot in a wooden maze. A maze-solving algorithm is an automated method for solving a maze.The random mouse, wall follower, Pledge, and Trémaux's algorithms are designed to be used inside the maze by a traveler with no prior knowledge of the maze, whereas the dead-end filling and shortest path algorithms are designed to be used by a person or computer program that can see the whole maze at once.
Pyomo allows users to formulate optimization problems in Python in a manner that is similar to the notation commonly used in mathematical optimization. Pyomo supports an object-oriented style of formulating optimization models, which are defined with a variety of modeling components: sets, scalar and multidimensional parameters, decision variables, objectives, constraints, equations ...
