+### ProcessBench
 
+We evaluate **EurusPRM-Stage 1** and **EurusPRM-Stage 2** on **ProcessBench**. 
+The threshold is obtained by converting the original score of each step using sigmoid function and iterating to find the highest F1 on GSM8k sub-benchmark. The threshold for **EurusPRM-Stage 1** and **EurusPRM-Stage 2** is 0.5015 and 0.5005 respectively.
+For leveraging the capibility of **EurusPRM** better, we add ``Step K`` (where K is the actual index of the step) in front of each step in **ProcessBench**.
