Best practice
When describing a system or process, use "operate by" to clearly indicate the governing principles or methods. For example, "The algorithm operates by analyzing user data."
Common error
Avoid using "operate by" when you simply mean 'to use' something. "Operate by" suggests a system or set of rules, not just utilizing a tool or object. For example, avoid: 'The chef operates by a knife' when you should say 'The chef uses a knife'.
