mathematical tractability meaning in English

便于数学处理

The result is satisfactory still . solution obtained is physically realistic because of the asoidance of assumptions made purely for mathematical tractability by usual methods
所得结果还是令人满意的，因为在求解过程中避免一些为在数学上易求解所作的假设。
Existed analytical performance models are always based on unrealistic assumptions for the purposes of mathematical tractability , such as only two processors are considered or ignorance of communication delays and rollback costs
Pads已有的解析性性能模型往往为了数学推导的方便，基于一些不实际的假设，有的仅在两个处理器上推导，有的忽略了通讯延迟和状态保存开销。
