Agent V4
Similar to V3 in terms of rolling out trade offers to multiple players but makes more aggressive trading strategies.
1. When I only offer to sell my properties in return for cash greater than the market price (and do not request for properties):
- If the other player has a lot of money, I try to exploit that by asking for 70%, 60% or 50% of the other players current cash since
he has a lot of money and can afford to give me so much for a monopoly.
- If the player isnt very rich, then I offer the property only if he is ready to give me atleast 1.5 times the market price.
2. When I am only ready to buy properties and have no properties to offer, then:
- if the player from whom I request properties is near bankruptcy, then I request to buy at 1.125 times the market cost else the
player has no incentive to sell it to me. He might as well make a sell property offer during his turn for a higher price from me.
- But if the player is rich, then I only offer to pay 0.75 times the market price since that property is not of much use to him and
might do me a favor by giving it to me.
3. When exchanging properties:
- I again exploit the other players current cash by asking for 70%, 60% or 50% if he is wealthy and can afford to spend a lot of money for a monopoly.
- If he does not have sufficient cash, I play it safe since I need to increase my number of monopolies and request for cash only = 1.5 times
the market price for my property and agree to buy his lone property at 0.75 times the market price.
Agent V3
This updated version of the agent can make trade offers with MULTIPLE players simultaneously.
All strategies available in Agent V2 is still available in V3
Note that this version of the agent also engages in the trade of only one set of properties like the previous version, ie
- only one property will be requested if it is a buy property offer or
- only one property will be offered if it is a sell property offer or
- only one property will be offered and one property requested during an exchange property offer.
Agent V2
NOTE: The background agent that could make_sell_property_offer is deprecated (available as background_agent_v1_deprecated.py)
This version of the agent can only make_trade_offer and accept trade offer. Trade involves buy or sell or exchange property offers.
Accept_sell_property_offer function is still available in case some different agent decides to make a sell property offer.
Ideally, accept_sell_property_offer() function should never enter allowable moves.
Make sell property offer can be replicated by making a trade offer that only offers to sell properties in return for cash
and doesnot involve a buy property or exchange property offer.
A buy property offer can be duplicated by including only requested properties by offering cash without offering properties.
Properties and cash can be exchanged which lets both players get an advantage of increasing their respective number of monopolies.
This version of the agent background_agent_v1 supports making sell property offers in return for cash via make_trade_offer,
buy trade offers and exchange property offers.
Note that this version of the agent engages in the trade of only one set of properties, ie
- only one property will be requested if it is a buy property offer or
- only one property will be offered if it is a sell property offer or
- only one property will be offered and one property requested during an exchange property offer.

'''
NOTE: The background agent that could make_sell_property_offer is deprecated (available as background_agent_v1_deprecated.py)
This version of the agent can only make_trade_offer and accept trade offer. Trade involves buy or sell or exchange property offers.
Accept_sell_property_offer function is still available in case some different agent decides to make a sell property offer.
Ideally, accept_sell_property_offer() function should never enter allowable moves.
Make sell property offer can be replicated by making a trade offer that only offers to sell properties in return for cash
and doesnot involve a buy property or exchange property offer.
A buy property offer can be duplicated by including only requested properties by offering cash without offering properties.
Properties and cash can be exchanged which lets both players get an advantage of increasing their respective number of monopolies.
This version of the agent background_agent_v1 only supports making sell property offers in return for cash via make_trade_offer.
Buy and exchange property offers are not involved in the trade.
