Web23 okt. 2024 · We use the CPLEX for MATLAB API to solve a MILP. In our case the bottleneck of the API is the limited functionality of indicator constraints. Whereas in OPL and the Java API an "if and only if" statement is possible, this functionality is missing in MATLAB. Java and OPL offers both options: z = 0 -> x == 0 (in case x != 0 => z=0 or z=1) Web13 apr. 2024 · In general, the CPLEX solver terminates with a relatively optimal tolerance in 10 − 4. The upper bound of runtime is set to be 14,400 s (4 h); the results marked by superscript 14 , 400 * indicate that optimal solutions cannot be found within 14,400 s, while the results marked by—means that we cannot obtain the exact output within 14,400 s.
