Wireless devices, such as field devices or repeater/relay nodes, detect the presence of anomalies in data packets that suggest intrusion. Upon detection of an anomaly, a wireless device sends a notification to a sentinel device, which determines if intrusion may be occurring. If so, the sentinel device downloads a spy routine to at least one of the wireless devices, which enables further investigation into and/or isolation of the intrusion. Since the spy routine is downloaded to the wireless devices, the spy routine can be used in conjunction with memory-constrained wireless devices. Memory-constrained wireless devices may lack adequate memory for storing both a main application executed during normal operation and the spy routine. The spy routine could overwrite one or more modules of the main application. Once executed, the spy routine could itself be overwritten by the one or more modules, allowing the wireless device to return to normal operation.

A pattern solution set for paper roll trimming to fulfill orders is generated using constraint programming and a heuristic. For every pattern generated, an objective function is evaluated based on the sum of waste factor and the variance of the quantity ordered for all widths in that pattern. The pattern that has the least objective function is chosen with the maximum number of sets possible. Orders are updated with the quantities left over and then the process continues, forming a solution tree, which serves as an initial solution set. The initial solution set is checked individually against the average loss of the solution set. Nodes in the solution tree having trim loss greater than the average loss are identified. Branches of the tree emanating from its parent are explored for better patterns. The process continues until all patterns are below the initial average loss.
