Question: a problem about the 'PointBid'

[sjtu-jason]

When I using the 'PointBid' class, I met with a problem.

I built a device agent. And I used ‘PointBid’ class to build its bidcurve by adding pricepoints.

If the quantity of pricepoints is small (e.g. 2 or 3..), it is okay. But, if the quantity of pricepoints is large (e.g. 7 or 8..), an error will appear: 'ERROR n.p.c.c.Concentrator$MatcherPart - doBidUpate failed for matcher concentrator'.

Would you please tell me what's wrong?

For me it is not really clear what your question is. Could you maybe show us some of your code?
Also, the structure of the Bid (or PointBid) is going to change a bit in PowerMatcher 2.1, which we want to release soon. If you like to you can checkout the powermatcher-2.1RC branch, maybe it helps.

If I use the below code, it is okay.
publishBid(new PointBid.Builder(mb).add(mb.getMinimumPrice(), 0.0) .add((price1 - 1e-5), 0.0) .add(price1, d1) .add(mb.getMaximumPrice(), d1) .build());

But if I increase the quantity of pricepoints, an error will appear. For example:
publishBid(new PointBid.Builder(mb).add(mb.getMinimumPrice(), 0.0) .add((price1 - 1e-5), 0.0) .add(price1, d1) .add((price2 - 1e-5), d1) .add(price2, d2) .add((price3 - 1e-5), d2) .add(price3, d3) .add(mb.getMaximumPrice(), d3) .build());
