Coin Oracle StripesThis color map involves a square tableau with horizontal stripes, each stripe being one of the four colors: white, red, yellow, or blue. These correspond to the outcomes, 6, 7, 8, or 9, respectively. This is essentially a one-dimensional map. For example, consider a square tableau of 160 by 160 pixels, with each stripe one pixel high. It is convenient to have a number of stripes that is a multiple of 8. To achieve the CO probabilities, we must have in each group of 8 stripes: one 6-colored (white), three 7-colored (red), three 8-colored, and one 9-colored. But if the colors are visible to the user, one might just choose the outcome desired, without participation of the oracle itself. To make them less obvious, we might mix them up. For example, rather than: 6-7-7-7-8-8-8-9,we might use 7-8-6-7-8-9-7-8.More deviously, we might even make the colors invisible. Revised 06 May 2002 by Ralph Herman Abraham |
