I have the following code:
payoffs2exchanges.put(point, exchange);
if (!payoffs2exchanges.containsKey(point) ) {
game.log.fine("yes");
} else {
game.log.fine("no");
}
It outputs "no". In other words, I add the key-value pair to the map, and then, immediately after that I check if the key exist and find out that it does not exist. Why?
I still have the problem with the key. The following code says every time I add a key I add a new key. And I know that it is not the case.
Integer[] point = new Integer[2];
point[0] = proposerBestScore;
point[1] = responderBestScore;
game.log.fine("In the getCloudOfPayoffs: found payoffs:" + point[0] + "," + point[1] + ". Exchange: " + exchange[0]+","+exchange[1]+","+exchange[2]+","+exchange[3]+","+exchange[4]);
// With the following block we ensure that every options (pair of payoffs) is represented by exchange with minimal number of moves.
if (!payoffs2exchanges.containsKey(point)) {
payoffs2exchanges.put(point, exchange);
game.log.fine("In the getCloudOfPayoffs: this option is new. We add it to the map.");
} else {
game.log.fine("In the getCloudOfPayoffs: this option is old.");
Integer[] exchangeFromMap = payoffs2exchanges.get(point);
Integer newSum = 0;
Integer oldSum = 0;
for (int i=0;i
