超时选项-T导致进程终止，因此它不返回任何中间值.如果使用-t选项(软超时)，则该过程不会终止.相反，Z3会在检查取消的某个点停止搜索.然后产生到目前为止***的答案.它对应于设置取消状态.我希望这对您有用.

The timeout option -T causes the process to terminate so it does not return any intermediate values. If you use -t option (soft timeout), then the process does not terminate. Instead Z3 will stop the search at some point where it checks for cancellation. It then produces the best answer so far. It corresponds to setting a cancellation state. I hope this will work for you.
