![]() By working together, Europe has the weight to shape an open global trading system based on fair rules – and to ensure that those rules are respected.So EU trade policy seeks to create growth and jobs by increasing the opportunities for trade and investment with the rest of the world. The development of trade – if properly managed – is an opportunity for economic growth.Together, the European Union's members account for 16% of world imports and exports. ![]() Europe is the world's largest exporter of manufactured goods and services, and is itself the biggest export market for around 80 countries.Every day, Europe exports hundreds of millions of euros worth of goods, and imports hundreds of millions more.Workers often deliver their services across different countries within a multinational or by specific service contracts.Īs investors thrive in a stable, sound and predictable environment, they are looking for investment barriers to be dismantled and investments to be protected. ![]() Thanks to the ease of modern transport and communications, it is now easier to produce, buy and sell goods around the world, which gives European companies of every size the potential to trade outside Europe. BlockWorld -> Runs the main algorithm which solves the Block World Problem using a single goal stack, and stores the appropriate actions in a queue and displays the same when the main stack becomes empty.The EU has achieved a strong position by acting together with one voice on the global stage, rather than with separate trade strategies.Įurope has become deeply integrated into global markets. Block Class -> Initializes a block object with its unique identifier.Ĥ. Predicate Class -> There are 5 predicates which we have used to identify a state correctly. Compound Goals, Single Goal and Operator are assigned different flags so that they can be distinguished easily on the basis of that.Ģ. Each goal has to recognized according to its type and processed accordingly. Goal Class -> The Goal Stack comprises of three different kinds of terms, all of which are goals in themselves. PreConditionList -> It consists of all the preconditions predicates required before the application of the operatorĭeleteList -> It consists of all the predicates which will no longer be true after the application of the operator.ĪddList -> It consists of all the predicates which are made true after the application of this operator.īlockWorld.java -> It consists of four classes :-ġ. Operator class helps us to represent these actions in an easy manner, and maintains three lists corresponding to every action. PutDown(X) -> Action to putdown block X on the table PickUp(X) -> Action to pickup block X from the table Unstack(X,Y) -> Action to unstack block X from block Y Stack(X,Y) -> Action to stack block X over block Y Operator.java -> This java file contains the Operator class which contains routines for 4 different operators. Here is a brief description of each one of them. The given program contains two java files namely "BlockWorld.java", and "Operator.java", both of which contains a number of classes and methods.
