This week the #puzzle is: How Greedily Can You Mow the Lawn? #geometry #area #volume #GreedyAlgorithm (Link at the bottom.) You’re mowing a circular lawn with a radius of 1 unit. You can mow in straight strips that are 1 unit wide. The fewest number of passes you would need to mow the entire lawn […]

#greedyalgorithm can be used to find a max-weight basis of #matroid, by starting from empty set and repeatedly adding one element at a time, at each step choosing a max-weight element among elements whose addition would preserve the independence of the augmented set
let u be min odd number \geq y/x, include the fraction 1/u in expansion, and continue in same way with remaining fraction x/y − 1/u. This method is called odd #greedyalgorithm and the expansions it creates are called odd greedy expansions.

Earth Mover Distance may be computed exactly using a #greedyalgorithm, and the resulting functional has been shown to be #Minkowski additive and #convex monotone
