Calculating Crime
When you think about math, you probably don't think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with
mathematical tools to help police find criminals.
People who solve crimes look for patterns that might reveal （揭示） the identity of the criminal. It's long been believed, for example, that criminals will break the law closer to where they live, simply because it's easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.
But Mike O'Leary, a mathematician at Towson University in
Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal's home base by combining these patterns with a city's layout （布局） and historical crime records.
The records of past crimes contain geographical information and can reveal easy targets - that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and
intersections are. O'Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal's patterns change with age. It's
