void EnterIntervalFinding_bn ( | node_bn* node, double low, double high )

Enters a likelihood finding for node equivalent to an interval extending from low to high: [low, high].

The likelihood outside the interval is zero, while inside the interval it is uniform (i.e., a "rectangular distribution").

This will not remove any findings already entered for node (it will accumulate), so you may want to call RetractNodeFindings_bn first.

If node is a continuous node (but discretized, see NewNode_bn), then low and high refer to continuous values the node can take. Then high must be greater than low.

If it is a discrete node, then low and high are state numbers, and so must be integers. In that case, the interval includes both end states (so it is okay if low = high).

If the net has auto-updating (see SetNetAutoUpdate_bn), then a belief updating will be done to reflect the new finding before this function returns (otherwise it will just be done when needed).

Version:

Versions 3.15 and later have this function.

Example:

    // This function will clear previously entered finding information
    // before entering new interval information.
    //
    void SetIntervalFinding (node_bn* node, double lo, double hi){
        net_bn* net = GetNodeNet_bn (node);
        int saved = SetNetAutoUpdate_bn (net, 0);    // turning it off can greatly aid efficiency
        RetractNodeFindings_bn (node);
        EnterIntervalFinding_bn (node, lo, hi);
        SetNetAutoUpdate_bn (net, saved);
    }
