Almost all programming languages support regular expressions. Many search languages allowed simple wildcards, for example “*” to match any sequence of characters, and “?” to match a single character. Non-programmers may use regular expressions in many situations just as well. In particular, business rules may need to define conditions that use regular expressions. Examples of such rules were specified in the DMCommunity July-2025 Challenge. Below is a possible OpenRules solution.

The new release 11.0.0 of the OpenRules Decision Intelligence Platform (http://OpenRules.com) simplifies the installation process, and the standard installation now includes various OpenRules samples and documentation. We also introduced advanced features to Rule Learner, Rule Solver, and Rule DB. The website OpenRules.com has been unified and now includes product-specific sidebars.
