Much harder than Can this pattern be made with dominoes?
Challenge
A grid of width \$w\$ and height \$h\$ is given, filled with 1s and 0s. You can place a domino somewhere on the grid only if both cells are 1. You cannot overlap dominoes. What is the maximum number of dominoes you can fit in the ...
Stack the rocks
This is a rock:
