CP# 4, Stinkbugs, Can We Stop Them? As starting point we will tray the following combinations in an initial toy 5x5 problem, within the 25x25 matrix. Let's take the 5x5 submatrix at the center of the 25x25 in blue (1) Along a row: (2) Along a column (3) Along the diagonal 4) Along the antidiagonal (5) Sum of all 5x5 elements Stinkbugs Have Spread to 41 States, can we stop them? If you don't yet know what a brown marmorated stinkbug Halyomorpha halys) is, consider yourself lucky. These invasive insects are marching their way across more and more of the United States, spoiling fruit harvests and driving homeowners crazy. The stinkbug species seems to have hitched a ride to the U.S. in the mid-1990s in a shipment of Asian goods. The earliest sightings occurred in Allentown, Pennsylvania, but in just two decades the hardy pests have spread to at least 41 states. 304 95 50 91 546 26 24 62 52- 232 85422 48 23 (1) The sum of one row is 33+48+23+76+52 = 232 304 (2) The sum of one column 81+97+85+8+33 A PR researcher have collected stinkbugs population in a 2.5x 2.5 km square field. In an effort of the United States Department of Agriculture who has been working to understand the threat stinkbugs pose and detect patterns in how they move. Top down the problem, and find the sum of bugs in a nx n small area (say n-5) which may signal their movement behavior in a larger area. In the 25x25 grid below, twenty five neighboring numbers have been marked in blue in a 5xs matrix. They represent number of bugs found in smaller area: (3) The sum of the diagonal is 81+7+78+81+52 299 (4) The sum of the antidiagonal is 33+28+78+9+37 185 (5) The sum of all 5x5 neighbors is 1135 Once we are able to solve the toy problem, the program code will become a user-defined function i.e., one targeting a 5x5 submatrix) and a search within the full 25x25 matrix should be attempted.
