您提到的“上个问题”并没有提供具体的背景或上下文信息,因此我无法直接给出相应的代码。不过,根据您的要求,如果您需要更新后的全部代码,请明确指出是哪个部分的代码以及具体的需求和改动点。例如:
1. **是否是指 `A* Search` 部分的 Java 代码?**
2. **还是指 `Automated Planning` 部分的 PDDL 代码?**
请您提供更多详细信息,以便我能更准确地帮助您。以下是两个部分的基本结构和示例代码,供参考:
### A* Search - Java 实现
#### 1. 定义状态类 (`State.java`)
```java
package uk.ac.hw.macs.search;
public class State {
private int x;
private int y;
private int gCost; // Cost from start to current node
private int hCost; // Heuristic cost from current node to goal
private State parent;
public State(int x, int y, int gCost, int hCost, State parent) {
this.x = x;
this.y = y;
this.gCost = gCost;
this.hCost = hCost;
this.parent = parent;
}
public boolean isGoal() {
// Check if this state is the goal state
return x == goalX && y == goalY;
}
public int getHeuristic() {
// Calculate Manhattan distance heuristic
return Math.abs(x - goalX) + Math.abs(y - goalY);
}
// Getters and setters
}
```
#### 2. 定义搜索顺序类 (`AStarSearchOrder.java`)
```java
package uk.ac.hw.macs.search;
import java.util.PriorityQueue;
import java.util.Comparator;
public class AStarSearchOrder implements SearchOrder {
private PriorityQueue<Node> fringe;
public AStarSearchOrder() {
fringe = new PriorityQueue<>(Comparator.comparingInt(Node::getFCost));
}
@Override
public void addToFringe(Set<Node> nodes) {
for (Node node : nodes) {
fringe.add(node);
}
}
public Node pop() {
return fringe.poll();
}
public boolean isEmpty() {
return fringe.isEmpty();
}
}
```
### Automated Planning - PDDL 实现
#### 1. 域文件 (`windfarm-domain.pddl`)
```pddl
(define (domain windfarm)
(:requirements :strips :typing)
(:types
uuv - object
location - object
ship - object
)
(:predicates
(at ?uuv - uuv ?loc - location)
(connected ?from - location ?to - location)
(has-image ?uuv - uuv)
(has-sonar-data ?uuv - uuv)
(sample-collected ?uuv - uuv ?loc - location)
)
(:action deploy-uuv
:parameters (?uuv - uuv ?ship - ship ?loc - location)
:precondition (and (at ?uuv ?ship))
:effect (and (not (at ?uuv ?ship)) (at ?uuv ?loc))
)
(:action move-to
:parameters (?uuv - uuv ?from - location ?to - location)
:precondition (and (at ?uuv ?from) (connected ?from ?to))
:effect (and (not (at ?uuv ?from)) (at ?uuv ?to))
)
(:action take-image
:parameters (?uuv - uuv ?loc - location)
:precondition (and (at ?uuv ?loc))
:effect (and (has-image ?uuv))
)
(:action take-sonar-data
:parameters (?uuv - uuv ?loc - location)
:precondition (and (at ?uuv ?loc))
:effect (and (has-sonar-data ?uuv))
)
(:action transmit-data
:parameters (?uuv - uuv ?ship - ship)
:precondition (and (at ?uuv ?loc) (has-image ?uuv) (has-sonar-data ?uuv))
:effect (and (not (has-image ?uuv)) (not (has-sonar-data ?uuv)))
)
(:action collect-sample
:parameters (?uuv - uuv ?loc - location)
:precondition (and (at ?uuv ?loc))
:effect (and (sample-collected ?uuv ?loc))
)
)
```
#### 2. 问题实例文件 (`windfarm-problem1.pddl`)
```pddl
(define (problem windfarm-mission-1)
(:domain windfarm)
(:objects
uuv1 - uuv
ship1 - ship
loc1 loc2 loc3 loc4 - location
)
(:init
(at uuv1 ship1)
(connected ship1 loc1)
(connected loc1 loc2)
(connected loc2 loc3)
(connected loc2 loc4)
)
(:goal
(and
(has-image uuv1)
(has-sonar-data uuv1)
)
)
)
```
如果您有特定的修改需求或遇到的问题,请详细说明,我会尽力提供帮助。
