A New Approach Breaks A Barrier That’s Stood For Nearly Half A Century – Planning The Best Route With Multiple Destinations Is Hard Even For Supercomputers

Computers are good at answering questions. What’s the shortest route from my house to Area 51? Is 8,675,309 a prime number? How many teaspoons in a tablespoon? For questions like these, they’ve got you covered. There are certain innocent-sounding questions, though, that computer scientists believe computers will never be able to answer – at least not within our lifetimes. These problems are the subject of the P versus NP question, which asks whether problems whose solutions can be checked quickly can also be solved quickly. P versus NP is such a fundamental question that either designing a fast algorithm for one of these hard problems or proving you can’t would net you a cool million dollars in prize money. My favorite hard problem is the traveling salesperson problem. Given a collection...

At The Forefront Of Black Achievement For More Than A Century Have Stood Black Sororities

In her speech at the 2020 Democratic National Convention Kamala Harris saluted seven women who “inspired us to pick up the torch and fight on.” All but two of them, one of whom was her mother, belonged to Black sororities.

Like her, I am a proud member of a Black sorority: Delta Sigma Theta, which I joined as a student at Longwood University in Farmville, Virginia. If I were in Harris’ shoes, accepting such an unprecedented leadership role, I, too, would have paid homage to my sorority as a way to thank those on whose shoulders I stand. This shoutout also resonated with me because I have resea...

How New Yorkers Stood Up to Amazon and Won

Queens activists, unions, and political leaders worried about gentrification and opposed the $1.2 billion in tax breaks offered to the retail giant. When Amazon announced in November it would establish another headquarters in Long Island City, in the Queens borough of New York, the reaction wasn’t all positive. A group of local activists, unions, and political leaders voiced their opposition to the $1.2 billion in tax breaks the city and state offered the retail giant. Many cities had actively courted the company in hopes of investment and jobs. But the Queens contingent also feared increased gentrification and displacement from the neighborhood and came together to fight the decision. In February, the resistance scored a victory when Amazon abandoned its plans in New Yor...
