Abstract: Approaches presented herein enable optimizing a hierarchical rule-based decision policy. An initial domain of values for each decision of a ruleset is extracted. Using the initial domain of values and a hierarchical structure of the ruleset, a reduced domain of values for each decision is computed starting from the lowest level decision. Each of the reduced domain of values upwards in the hierarchical structure is propagated upwards. A completeness and consistency analysis for each decision is then performed based on the propagation to identify any missing and/or arbitration rules for the policy.

Abstract: A method, device, and/or computer program product operates a touch-screen device. One or more processors detect a first moving touch on a touch-screen, where the touch-screen is able to detect a presence of the first moving touch but is not able to detect an amount of pressure being applied by the first moving touch. The processor(s) detect a simultaneous second moving touch on the touch-screen, and detect a line being drawn on the touch-screen by the first moving touch. The processor(s) calculate a calculated pressure for the first moving touch based on a distance on the touch-screen between the first moving touch and the second moving touch while the line is being drawn on the touch-screen by the first moving touch, and then adjust a thickness of the line being drawn on the touch-screen by the calculated pressure for the first moving touch.

Abstract: A method, device, and/or computer program product operates a touch-screen device. A first touch at a location on a touch-screen is detected. A second touch on the touch-screen, which occurs simultaneously with the first touch on the touch-screen, is detected. A pressure of the detected second touch is calculated and assigned to the detected first touch. A specific touch-screen output is generated according to the location and assigned calculated pressure of the detected first touch.
