For those who are interrested, I solved this issue by creating my own MongoDBOuput in a tJavaRow. In this way, I am more able to control the creation of my JSON schema. For example (in a tJavaRow): /*Get the MongoDB connection*/ DB db = (DB)globalMap.get("db_tMongoDBConnection_1"); /*Get the collection*/ DBCollection coll...

First of all let's observe that if you will traverse some edges multiple times in the optimal solution, then all these edges will have same reward (otherwise it's more profitable to traverse the edge with bigger reward more times). So without loss of generosity we can say that you will...
