These examples in Java use Concert Technology. The following examples are delivered with CPLEX in IBM ILOG CPLEX Optimization Studio.
Avoid Global Variables: Minimize the use of shared global variables among threads. Instead, use thread-local variables or pass data explicitly between threads. Immutable Objects: Prefer using immutable objects as shared data. This eliminates the need for synchronization when accessing such objects. Vola...
