program cartridge

基本解释

By using the Constrained Variable Metric method, an optimization design model of the cartridge is established, and created a computer program, and then worked out the optimized result.
採用了約束變尺度法建立了乾擾子彈的優化設計數學模型，且編制了優化設計軟件，計算出了所優化的結果。

The machine does not allow modifications to its ROM (because it has an O in the middle), but the team was able to use a technique called return-oriented programming to modify how the machine executes existing code, taking the bits they want and, ultimately, devising a way to re-program its behavior by simply inserting a cartridge into a slot -- presumably after blowing on it for good luck.
